Correct, services cannot tell where you are coming from when you are using Tor. However, the service itself has no such protection.

With the crackdown that is occurring on the internet, I think everything is going to have to go into hidden services to remain censorship resistant.

Edit: I think it best to prepare for a world where the only use for the ClearNet is to download Tor, similar to how the only use for Microsoft Edge on Windows is to download Firefox.

Eventually, there may come a day where the clear net is just not used at all.
