If you don't like their games then don't buy them. I don't know what else to say beyond that.
Personally, I will buy Dragon Age 3. I have no desire to see BioWare close down. I'll continue to ignore microtransactions, but it seems to be a popular feature, so it probably won't go anywhere. I have zero problem with Day One DLC, though, and don't really understand why it's such an issue. As for tacked on multi-player, I can't blame EA for that one bit, not when the people who argue against restrictions on used games aways say, "add more value and I won't trade the games in." It's directly and completely a response to that.
I'm not much of a fan of EA and some of their practices but I'm also not going to condemn them too harshly for trying to survive as a business. I'll buy the good games they make and ignore the bad ones, just like with anyone else.
