I mean WWW is not owned by a single entity. All those companies you mention are replaceable. And the same is true about those parts that are patented or copyright protected; something Berners-Lee refused for html. I guess something similar happened with JavaScript. These languages are then free just like the spoken ones.
Apple decided not to include floppy disk drives in one of their computers and it seems everyone else followed suit. I'm not saying the decision was wrong just that in pursuit of the cloud other local storage devices might just go the same way, fait accompli.
Yes the net has become terribly concentrated and will become more so as less companies control bigger server farms, just as, in its case because of all the failures, the financial sector has become more concentrated than ever before.
I think the problem is when the general public get mixed up in things corporate, which is true with server farms. If banks were able to add personal mortgages to unrelated instruments in their derivatives, maybe IT can do something similar with access to information. Then if one farm or corporation went down all may be affected like the Japanese national grid after the Fukushima tsunami or any of the other OP concerns.
I think your idea of distributing information is well worth discussing (even though you spelled PRON wrongly).
