Thanks. I think we've always had the ability to publish content on the internet without relying on external services, and we still have. It's just not something that most people are willing to do, because it takes expertise and resources, and corporations can do it better by specializing in providing these kind of services. This is why people use them. For the same reason people don't usually make their own clothes, furniture, etc., either. Specialization and division of labour allows us to be much more productive and as a result enjoy a higher standard of living than we would if every individual had to produce everything they consume themself.
