Serious question, why do we give so much power to these tech firms such as Google, when really the solution is decentralization. We have some solutions for money with bitcoin, but there still doesn’t seem to be a viable alternative with a search engine that is decentralized?
Just the fact that you have many providers is a already a UX challenge. Either you have a “default” provider were everyone will flock (for example gmail for email), making decentralisation pointless or you force people to chose between many smaller providers, and most won’t want to make such a decision before even beginning to use the service and just leave.
I don’t see how that is challenging for users unless they are so lazy that they won’t even change any setting on their device regardless of how annoyed they are. If the app has a directory of instances with their bios linked it can make it easier for them.
