> If you enter into an agreement with someone

Upon review, it looks like you don't have to enter into an agreement with anyone in order to use this software, except its authors under the terms of the AGPL.

> exploitative behavior

Even if you want to frame it like that, it doesn't look good for you unless you assume we're imbeciles who don't keep score. You do not have any right to complain about exploitative behavior when you willfully exploit hundreds of millions of people by 1000 units and they "exploit" you by 1 unit in return. You're still a net exploiter in the relationship.

> when you know that they will continue to hold up their end

That's a lie, corporations unilaterally alter the terms of service without offering compensation all time.
