You need to check your history book. The Internet was paid for by the government and slowly allowed to be handed over to corporations over two decades once it was already long established. Many advances (including computers that you claim are corporate gifts) are actually creations paid for by governments (typically for military purposes) and then handed over to corporations over time for civilian use and implementation.
"...Thus, by 1985, Internet was already well established as a technology supporting a broad community of researchers and developers, and was beginning to be used by other communities for daily computer communications. Electronic mail was being used broadly across several communities, often with different systems, but interconnection between different mail systems was demonstrating the utility of broad based electronic communications between people....This process of privately-financed augmentation for commercial uses was thrashed out starting in 1988 in a series of NSF-initiated conferences at Harvard's Kennedy School of Government on "The Commercialization and Privatization of the Internet" - and on the "com-priv" list on the net itself..

Also, claiming that some form of fair competition exists between companies is either a misunderstanding of how modern MSCs (multiple service carrier) operate or a blatant manipulation of the truth to suit a rant. No company can or will attempt to overbuild another MSC in a zone unless one of them is AT&T (in which case you can actually get government grants to over-build them, and money from AT&T at times as well so they look better). Between franchise agreements and city divisions where cable companies will cut a city in half (effectively choosing to "compete" only in certain regions where there really is no competition) customers don't have any semblance of real options.
