Indeed, confusing terminology. I consider that collaborative document editing is the activity, cloud hosting vs P2P is the technical implementation.
Like it or not, nobody much is doing the latter because it’s much harder to set up and the available cloud solutions provide a much (much) better user experience. I don’t say this a better situation but it’s the way things are.
Realistically, there’s going to be no way to stop this. It’s too useful. It works and most people appreciate it. I know this because I have visited southern China recently. I’ve seen the train stations and coffee shops where people now think nothing of leaving their belongings completely unattended. This level of surveillance effectively makes petty crime impossible. It’s widely seen as progress, in a way it is progress, and there’s no going back.
The challenge remaining is to keep some level of democratic accountability over our governments. That’s feasible but it’s not going to be easy.
