Vendor lock in. I will not touch any IM services that is not completly open (client and server) and federated. I am looking for matrix.org that uses Olm [1] for E2E encryption.
The open web is still there. There are just many people that chose to not participate in it. There are still many who do and will probably do so for a long time. The one problem might be funding, but people will always think of something.
People are thinking of ways to break the open web too. Witness what just happened in India and was narrowly avoided because of hubris.
To add: there's still more attempts to break NN in India.
The civil groups which are being formed don't have the same environment or support that the first world has developed after years of civil liberties battles.
So yes, people are always thinking of something. It's just that the time to defend the commons is here.
