This is a direct consequence of centralization of services. We're doing this to ourselves.

You say "we" like it is the population of internet users. They have no choice in this other than to use whatever sites are available. It is the megaEvilCorps that are doing it to us. They start with a novel idea that is rewarded by lots of users. They then decide to weaponize their site against us to become money printing machines. They then use that money to buy up any competition which artificially limits the end user's choices. WE aren't doing shit to ourselves. Profit seeking megaEvilCorps are doing it to us.

On top of the megaEvilCorps are evilScammyHackers that have made the internet a dangerous place. So entrepreneurial minded folks came up with some cool things to help protect users and site owners from these evilScammyHackers. Problem is, it takes scaled services to do it which again takes money which naturally limits those that are able to provide those services. This is again not we doing anything to ourselves.

If you mean we has a species, then sure, but that's a really stretched definition of we

It seems like you wanted to ask a question but avoided using question marks so there isn't much I can do here.
