Bioware is Canadian, not US.
Also, keep in mind that to even have a case you'd need to show that the company had ample time after becoming aware of the bugs to fix them. A few weeks is NOT even SLIGHTLY enough time; especially when 2 of those weeks are considered holiday.
Being upset over the state of the game on some people's systems is fine. But some people here seem to jump the gun too fast. I mean, petitions and lawsuits? Give them time to try and fix things. Acting like children won't get you what you want any faster. =/
You do realise that DAI is literally inaccessible for certain disabled people right, and Bioware has done jack **** about this issue since release and it honestly should be a top priority (among others) because being excluded from an experience and it's not even your fault is frankly horrifying. I mean, if they have the time to pump in two more romances (Cullen and Solas, just before release), then how the **** didn't they catch & fix the horrific subtitling and text. (Which is a disability & health issue.)
In fact, they practically released DAI as unplayable flat out for last gen. There are still game breaking glitches and so many problems with the last gen release and they've managed to fix minor problems like extra save slots for PS consoles over the game breaking glitches. It's poor optimization and could be viewed as a money grab.
If they're going to sell a product, they have to make sure it works and is worth the money at the market they aim at, not botch the entire thing up and then do nothing about it so far. (It's been over a month now and it's still largely broken. Bioware is a LARGE company. They haven't even addressed some of the most basic ****.)
2 patches, mainly PC-centric, game inaccessible, game still broken, no word from Bioware or EA about the state of the last gen consoles, false advertising and the list goes on and on and on. Honestly, your problem should be with the companies, not the customers that got screwed over by a botched deal and are rightfully angry about it.
