Control over your data is part of anonymity. Sure, everyone will know the service belongs to you, but you'll be in total control over who knows what exactly. To most people not in the eye of the law, that is most of the anonymity they require.

Also, services like TOR exist. Both on the hosting and user side.

If you think TOR is anonymous then I have a bridge to sell you. It's far more likely a fed is going to record your activity on TOR than on a standard open web connection.

The point of TOR is that while it can be detected, at the entry nobody knows what you're sending to whom, and at the exit nobody knows who is sending what. The fed sniffing my TOR connection can't really do anything with it.
