Yes, they are.

Often times there’s just no reason to package a web app into an app container.

They pledge to defederate from Meta, I’d go one step further and defederate from any instance that federates with Meta.

They shouldn’t just defederate from Meta, they should defederate from any other instances that federate with Meta. Like a firewall against late stage capitalism

I think there should be an alliance of instances that defederate from any instance that federates with Meta.

A bit pessimistic though.
