"The Internet and World Wide Web are [...] a decentralised, mesh based network,"
It was, maybe, in the very beginning . Now it's an highly centralized system when most contents are stored by a few megacorps server and fashion dictates where little serfs have to go to store their little gems.
Look at how much Google and Facebook control contents - email, photos, videos, blogs.... how many services run and are stored on AWS or Azure? All the code was in GitHub, and only the hatred for MS will make some migrate to other shores, until a new big centralized service becomes fashionable, and moths will fly to it and store everything there.
Google is exactly scared that if the loopholes that allowed till now to become a monstrous collector of everything without any liability are closed, it cannot sustain such scale with little costs and huge profits, and then Internet yes, will break into smaller pieces, in a positive way, because it will return to be much more diverse and de-centralised one.
Maybe you'll still need a search engine to find a video, but there won't be anymore a chance that 99.999999% of the times it will be hosted on YouTube...
