I don't think a rule along the lines of "Doing $FOO to a corporate is forbidden, but doing $FOO to a charitable initiative is fine" is at all fair.

What "$FOO" actually is, is irrelevant. I'm curious how you would convince people that this sort of rule is fair.

The corp can always ban users who break ToS, after all. They don't need any help. The charitable initiative can't actually do that, can they?
