I use a lot of "free" online tools but I have some redundancy in there in case one fails - for instance, I use Slideshare and Slideboom for my online presentations. I use Google Docs and I use Scribd. I decided this early on in case someone's server was on the fritz and I was travelling. Now this redundancy is especially important when companies are looking to "monetize their assets." It is amazing how short-sited business people can be. How do you monetize a network? What do you charge for the learning and connections that happen? All of the great work that people did in these networks is swept away to "capture a big opportunity." Why not partner with education institutions, UNESCO, and other governments to harness those networks for everyone's benefit? That would be a far greater opportunity (and maybe even more lucrative) than any current business model could conceive.
In the meantime, we should be pushing more for open source tools, platforms, and public hosting of those open source tools.
