I think the above discussion is about whether they have to, not whether they can. Zoom can ban all of their users if they want to, but presumably they only will do so if pressured, because businesses want users and also suspending accounts is bad press. By the way, you're also allowed to be outraged by what a business does even when that business is acting within its rights.
I didn’t really care until now - and I won’t use zoom for any more personal conversations and am about to email my employer to move away from
Zoom for this reason. So yes bad press?
