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.
If you agree to $X but then don't do it: you're a liar.
The terms might be shit. But if you agree to shit terms you should be bound by shit terms. In the olden days: "I gave my word as a gentleman and a scholar" or "a deals a deal, even with a dirty dealer"[0].
Going back on a deal is not ethical; end of.
[0] I think it from Futurama.
Furthermore, these "use the service or not" agreements is like saying "accept a government or leave the country". Being handed an ultimatum saying "agree or you can't participate with your peers culturally, and potentially can't even access other local services such as government announcements", that's basically not a deal as there is no negotiation, that's being informed by greater powers of the pound of flesh they expect to extract.
Yes, yes I know the law says if you don't agree then you should simply not use the Internet, simple as that. That's clearly not even a possibility to be a functioning member of society at this point, but I guess it'll take some time for the law to catch up.

You have never been presented any TOS nor agreed to anything if you don't have an account.
If artists and youtube don't want us to use their 1 and 0 the way we want, they can pretty easily lock them under registration and payment. The thing is they don't care to do that, so they cannot complain.
No, you're unreliable.
