It's not that I'm siding with EA (because I hate that company) but, unfortunately for us, we are a small minority in the gaming world. I love what achievements have done for gaming and I love working to get them, but a lot (not all, but many, especially the larger ones) don't give a damn about whether or not the achievements are good, fun, or even unlock at the required critera. If Microsoft didn't make all games come with achievements, I have a feeling that many would not. Therefore, when 20,000 gamers complain that achievements don't unlock, etc., there are 20 million gamers that literally could not care less, which makes the companies not care because, ultimately, -20,000 gamers is just a drop in the bucket to them.
TL: DR = Don't stop caring, but don't get surprised when they don't care.
