or charge you and try to make a profit for a service that isn't free. I bet you get paid for what you do right?

Covering up the signs for a bit isn't in my opinion that bad...akin to protesting in front of the building. But doing something else detrimental to the business...that would become dangerous to more than the specific parties mentioned and I would regard it as a form of terrorism for profit or not. I think Anonymous wouldn't take it much further than organizing a bigger group to run whatever code they need.
