> I think AGPL would make it less useful for the honest people

I don't understand what you mean here. AGPLv3 guarantees the four essential freedoms to all users. It only restricts developers from removing users' rights, like the GPL family.

> On top of all that I don't know if it would be possible to sue companies that have been given de facto legal immunity to steal IP.

For that we should support NGOs fighting for users' rights like https://eff.org.
