You don't address my specific point; namely that it is not only possible but relatively inexpensive for any nation-state to compromise users' anonymity on Tor en masse not by cracking its cryptography but by running >50% of the nodes themselves.
a bit of a pedantic note: If you want to control 50% of the servers by adding servers, you actually have to double the total server count... ie, 8k servers now, if you want to control 50% you have to add 8k of your own servers for 16k total servers ...
Indeed, but my proposition is that they already did that, some time ago. It's just such a small amount of money that it seems unlikely that they _didn't_ do this.
