No doubt. All the more reason for client devs that care about freedom to give users choice, transparency, and control over any algorithmic content feeds, as those kinds of feeds are obvious ways for advertisers to utilize user data and manipulate (aka, censor) what content is in them. I don’t think we should expect that they won’t. I think we should be ready for when they do it so that the user has the tools in place to be in control. 

 Absolutely.

If Nostr goes down the P2P path or gift wrapped messages path, then it would severely hurt any data model. 

 Data models aren't hurt by private solutions. It's private solutions that have to keep up with the efficiency of shared information to be competitive.

This is the price of anarchy.
