My Giant hybrid is 4 months and 300 miles old.
On the way to work the bracket holding the rear derailleur broke, queue big mash up of chain/spokes/derailleur and bike come to a stop.
Broken bracket is aluminium. Bike shop say its unlikely to be warranty covered, usual cause of this is bike being dropped. Strikes me the part isn't tough enough for the job.

Come on, you can't say all Giants are junk because yours had a bit of a mishap. Or maybe someone has to tell Degenkolb that it's not his hairstyle which is crap, it's his bike...
Are you sure the two events weren't reversed - a poorly-lubricated chain can twist and get caught in the jockey wheels, pulling the derailleur off its hanger? It'd be very weird for the mech hanger to just snap of its own accord. Had it had a knock?
If it's done damage to the frame where the hanger sits, I'd put in a warranty claim, but the mech hangers are meant to be sacrificial to an extent - source a replacement from the hundreds of annoying designs, buy a new rear derailleur, and chop on.

As above, it's sacrificial. You sacrificed it somehow 
Thanks - I didn't know that. As far as I know its not been bashed. Not ideal that it can break so easily and damage a bunch of other stuff when it goes...Giant website says its reliable, tougher, city proof, designed to last....
Not doing very well at that today!

Trust me, you'd rather trash a mech and damage a few spokes than have the whole lot twist up and wreck the frame. Frangible mech hangers are a great idea.Giant website says its reliable, tougher, city proof, designed to last....

However, unless you were very unlucky I'd bet that the issue was caused by the rear mech being poorly aligned, the hanger itself being poorly aligned (it's amazing how out of true most are even on new bikes), hamfisted shifting or some combination of the above.
Hmmm?
My Giant Anthem MTB was supplied with a spare mech hanger from new. Over 1300 (mostly off-road) miles on it since March this year, including a testing race at Battle on the Beach in it's first couple of weeks.
I've had one problem in that time and it was the (KMC brand) Quick-Link failing on the chain. Can't blame that on Giant though.
As others have said,the mech hanger is a sacrificial part designed to prevent serious frame damage in a chewed-up derailleur event. I've seen the results of such an issue three times now. 1st time was a local lady on her commute in the dark. As far as we could tell, as I used a Leatherman to get her bike push-able at least, the problem was caused by a tiny but very tough twig getting caught in the pulley wheels and jamming things up.
2nd time was my old mountain bike. Just plodding along on an easy byway, when for no apparent reason the hanger gave way and the mech was dragged round the cassette. I managed to bodge a 'field single speed' conversion for that and ride home. I suspect that one was down to some cheap jockey/tensioner wheels I'd bought a long time ago. All mended now, and the hanger replaced.
3rd time was on an old steel road frame, without a sacrificial hanger. That was a nightmare, and badly bent the mech mounting point and axle drop-out to the point where the bike is off the road right now awaiting cash and/or a repair decision before it can be fixed. If only that one had had a sacrificial hanger - I could have got it back 'on the road' fairly swiftly.

Go to http://gearmechhanger.com/ for a replacement. Top bunch!
I think you have just been unlucky, annoyingly when something like this happens it costs more than just a mech hanger.
Mine went on my Giant (MTB) but that was after circa 3500 miles with some serious abuse - A branch forced my mech into the wheel and a similar thing to you happened. New Hanger, Rear Mech and Wheel straightened (which ended up with being a new wheel after the next 2 rides) later and I was set to go...
Subsequently my frame cracked (unrelated) took it back to my local Giant store and within a day a replacement was confirmed - I was quoted a 12week replacement period though as my frame wasn't manufactured anymore (you'd think they'd offer the latest frame?) 12 weeks is up tomorrow so fingers crossed it will be here anytime soon!

Mate think yourself lucky! When I had that happen it was going up an 10% climb and through me off into the road, then down a ditch, I was still clipped in down the ditch with my bike above me on the road, I couldn't get out the ditch! As there was no hanger (steel frame) it broke 2 spokes, a derailer and bent the frame a bit!
Mine was caused by my dogs knocking my bike over, bending it a bit, I bet yours probably got a knock of similar
What happened to you could happen on any bike , unless you fancy riding fixed, single speed or hub gears you always gotta be careful of it

After my Orange Crush was stolen, I got a Giant Anthem with the insurance payout. It wasn't the cheapest one, but the next one up. I wasn't impressed, it felt cheap and sounded cheap and need a fair bit of fettleing to get right.
Luckily (well not really) the thieves returned 6 months later and stole that too. I went with a Merida 140 900 after that and the difference is night and day. The Merida is better specc'd, better put together and rides much better.
I should add that before the Orange I had a Giant Team AC that was a very good bike.
