To be fair to the parent, he does have a point. You are in no way entitled to the free use of such a service. It's great that it's provided and all, but in the end, there may be some, or no, reason, that they want to pull the plug, on you, on a subset, or the entire service.
"Entitled" blogs, rants and the like (and to be clear, this entry didn't strike me as particularly entitled, but disappointed) are more the act of petulant children.
I run an online service that has been going since 1998. There are lots of instances of abusive behaviour there. We have a whole range of ways to deal with these and we feel that as long as users operate within the terms of service that they have a right to participate. Selectively withholding access for capricious reasons would be discriminatory behaviour. On top of that you never know how big a role your free service plays in someone else's life. Banning users / deleting content is a decision that you should not take lightly as a service provider.
