Doesn't this just identify you as "that one guy who blocks fingerprinting"?
It's similar to when you use Linux or an obscure privacy-preserving browser. You've made yourself way more unique just by doing that.
(I'm not sure how the math works out though, vs. actually running all that nasty tracking stuff.)
There are dozens of us!
But, yeah, anti-fingerprinting is still a useful signal if less people do it. So more people should do it; especially if they're less likely to be targeted.
"More haystack" makes their job harder.
