Tor Browser? Perhaps, but their stated justification is that they were always leaking that via JavaScript and other ways, that Cloudflare was detecting the discrepancy and blocking you a lot more, that they're still spoofing just one of three values (Windows, Mac, Linux) which now matches the JS property, and that they'd like to redo it properly in the future. Seems reasonable to me.

Tor browser's philosophy is that everyone should be fingerprinted and it's fine since they do everything they can think of to try to make that fingerprint identical to everyone else using Tor browser.

This is kind of crazy since there are new fingerprinting techniques all the time and if they miss even one data point the whole game is lost. The smarter movie would be to make sure that fingerprints are unique/randomized so that even the same person looks like different people but for some reason they're confident they can account for every possible identifying metric 100% of the time.
