There are a couple of reasons. One:

1. I’ve come to realise recently that a company, while providing convenience to users, is a single point of failure enforced by institutions who find it disruptive. So we have to go underground a bit.

2. With decentralised protocols, this is now possible.

3. Also meaning those who create and provide value, should have the option to anon, less they are subject to coercion as well.

There are a few other reasons, where this optionality makes sense, as well.
