What do I do when nobody answers my e-mails anymore, and nobody answers my questions online?

I have sent many e-mails to companies and asked numerous questions on here, which just go unanswered. No reply whatsoever. They are not rude, unreasonable, or in any way mal-intentioned.

I've noticed this in recent years, that even websites that "welcome feedback" and seem to encourage you to contact them just won't respond. They waste my time by making me sit here and write them carefully worded and polite e-mails with questions, which they then just ignore.

I don't get it.

And this website (and others) are the same. Forums. Any place online. I ask questions, make suggestions, report bugs, etc. No response. It's as if I were offline in a padded cell and just imagined having sent the messages.

This has been happening so frequently and consistently now, for so long, that I'm seriously wondering what the point is even trying anymore.

What could possibly explain this total shift in helpfulness? I understand if somebody doesn't want questions or even feedback, but then why the hell do they put up a big form or e-mail address and claim to "welcome your thoughts" and wording like that, when they clear don't?

Why have support forums where nobody looks/cares? Why run mailing lists where nobody responds even after months or years? Some bugs are literally 20 years old by now and still aren't even assigned!

I feel like I'm going crazy. There are so many unanswered questions and unresolved problems in my "computer world" that I find myself utterly crippled, and all these program, websites, services, APIs, etc. might as well be run by robots in terms of being able to communicate with them.

I truly don't understand it. How did this situation come to be?
