like how not being able to sign up for something with tor and monero is a privacy violation, it’s not.

Note that "secrecy" and "privacy" are often understood in Security lingo as different things. One protects confidentiality, the other one protects anonymity.

It's possible to have one and not the other...

You can have a very private system through onion routing but have the contents of the messages exchanged be in plaintext, open to the public. Nobody will be able to know the one who wrote the message was you. But they can see the message. (then there is privacy, but not secrecy).

Or you can have very strongly encrypted communications (say HTTPS) but have the DNS exchanges (or the TLS handshake, or the IP addresses) be in the clear, so people in the middle (eg. your ISP.. or your workplace tech guys) can know exactly that the packages are sent by you and where you sent them, even if their content is encrypted. They can know which service you tried to access to, for how long and how many times (so you have secrecy, but not privacy).
