Tor specifically doesn't resist pervasive flow monitoring, and their lack of being able to resist that attack is discussed thoroughly in the documentation, at least twice (both general usage and in the threat models section).

The attack you say stands out is literally just implementing the most obvious thing that Tor explicitly doesn't defend against. It's just a demonstration that Tor's threat model is accurate, and not a weakness in Tor that people were unaware of.

The you had a knee jerk reaction to not use Tor for what it's good at when you realized it can't do everything is the all-or-nothing, it must be perfect mentality that is the enemy of good.

It's people like you, with your all-or-nothing extremism that undermine reasonable discussions about partial steps we could take.
