To play the devil's advocate, does a volunteer have more incentive to keep your data private, or a company whose very business and reputation relies on keeping it private? Is a network that can readily and easily be infiltrated by malicious parties "for free" more trustworthy, or a private network locked down to trusted machines by security engineers, audited by third parties?

Because there is enormous incentive to deanonymize Tor. In 2020, nearly 25% of the network was controlled by a malicious attacker. [1] You had, then, a 1.5% chance of complete and total deanonymization by a single party - a near-certain chance of deanonymization if you heavily used Tor. And this is without any traffic correlation antics.

Turning off the devil's advocate, most "trustworthy" VPNs are almost certainly intelligence gathering operations, claiming "no logs" in court but in reality being a tool for parallel construction. It's too valuable a position for the 3LAs of the world to not have some ownership and stake in major VPNs. Crypto AG-style.

IMHO there is no hope for modern anonymity. Interesting connections will be logged for future deanonymization with quantum computers. In the meantime, mixnets like Nym [2] might emerge to be our saving grace.
