Have you replied to the linked threads with meaningful, useful input on the issues?
Of course. I help where I can, but it's not my responsibility to fix bugs in this game.
I like that EA is being more transparent about issues, that it has created a laundry list, etc. But I also dislike it when profitable companies rely heavily on volunteers or "fans." EA can't know about bugs that aren't reported, so players have to submit bug reports (I think asking for feedback and reports is good), but volunteers doing a lot of forum moderation, troubleshooting, and categorizing of bugs has always felt a bit off to me. To me, as an outsider looking in, and in consideration of the state of Sims 1 - 3, it seems like addressing bugs is not a huge priority. IF that's actually the case, it must make sense from a business POV, but as a consumer, it also encourages me to avoid purchasing certain packs because I don't want my game to break.
I have sympathy that some issues are hard to fix, but as a consumer, that's not really my problem. I'm sorry, but if something is broken (regardless of why), I'm much less interested in purchasing it.
