True. Tor, Tails, PGP (GPG), Monero etc. are not magic: you can be still de-anonymized especially if you post your private info by yourself. One thing I’ve been feeling a little uneasy about Tor is, the project is largely funded by the US Government itself, and in the past the US intentionally weakened Netscape browser (*1). While I would like to believe that something similar is not happening to Tor Browser, I’m not an absolute believer of Tor (like you said, there may be bad actors in the Tor network too). I might be feeling somewhat more comfortable if Tor Project were based on Europe, not the US.

Nevertheless, using Tor should be surely safer and more privacy-friendly than just using clearnet. Tor Browser is FLOSS and free as in free beer too. Using it when you’d like to be anonymous is not such a bad idea, especially if your instance is Tor-friendly.

Another example of intentional back doors standardized by the US is: https://wl.vern.cc/wiki/Dual_EC_DRBG?lang=en Onion - http://wl.vernccvbvyi5qhfzyqengccj7lkove6bjot2xhh5kajhwvidqafczrad.onion/wiki/Dual_EC_DRBG?lang=en

Get Tor Browser and/or Tails OS. When privacy is important and you need to be anonymous, use only Tor-friendly instances only via Tor (never once log in showing your real IP - if you accidentally do that, you’ll have to re-create another account as a different person).

When an email address is necessary to sign up, get one anonymously (again using Tor Browser), from a privacy-centric company or group, e.g. Tutanota, Disroot. Needless to say never ever use Gmail. https://tosdr.org/en/service/217
