Earlier quoted context omitted.
Considering the existence of the long support thread, Apple doesn't seem to be trying to suppress this issue. And that poster has many posts, so isn't being targeted either. Could it be the posts were deleted legitimately? Some people in that thread are pretty angry and may have let it get the better of them.
Given Apple's less than ethical history, I'm not sure it's reasonable to give them benefit of doubt. They might have an excuse that fans can believe, but the real reason is to suppress bad press.
Your assertion doesn't match the plain facts though.
We know Apple isn't suppressing this issue because there's a long, detailed thread about it on their own discussion site. If they wanted to try to suppress it, they would surely include that but didn't.
Also, suppressing information about problems to prevent bad press can't work anyway, since Apple only controls its own litter corner of the internet. If Apple didn't allow discussion of this issue on their board, it would be discussed elsewhere and generate the same bad press. If we suppose Apple tries to work in its own self-interests, they wouldn't bother with deleting posts to prevent bad press since it can't possibly work.
Meanwhile, there are obviously legitimate reasons to moderate postsm, so the fact that posts are being deleted doesn't seem nefarious on its own. There are angry people in that thread and angry people tend post things that need moderation.
I mean, I don't know. I'm open to the possibility that Apple is doing something bad. But so far, there's really no smoke, much less any fire.
