Between the title and the quoted, I think you have used up your hyperbole quota for one day.

I guess I don't see the issue. The internet is a large piece of infrastructure on which citizens and companies can publish (almost) anything they want. Lamenting that for-profit ventures have tried to wall off their parts is curious, as I am not sure how that impacts me or my decisions. I don't facebook, I don't tweet, and I could not care less that these things exist. (Not entirely true, but my objections to them would be off-topic.) The world is a very large place, and there will always be people who hang out in the more distant corners of the net, you can go be with like-minded people and talk about the good ole days of (insert bygone era here).

Now if you are lamenting this because you want a piece of the action and the big kids are being bullies, then I suppose my answer isn't going to comfort you any. But for just simple usage, I think this is a tempest in a teapot.
