It makes sense that they treat Tor like a probable adversary, but the cost analysis seems really flawed.

Sure, the proportion of requests passing through Tor are more likely to be malicious, but given the bandwidth constraints the adversary seems limited.

The costs aren't only the lost business from people like you, but people who should use Tor giving in. There's some wisdom to people even researching something as mundane as what their dog ingested using anonymized services, much less other medical questions.
