Yeap, I think you're right regarding the fingerprinting issue: Tails has
an ad block while Tor Browser doesn't have one and this can be
fingerprintable.
It's a deliberate choice of Tails to include an ad blocker, part of the
decision is that the user experience of a web without ads is soooo much
better and also political (we don't like ads). And we believe that these
two points in favor of blocking ads overweight the downside in terms of
fingerprint.
And, spoiler: I think I saw Tor Browser reopening the debate on whether
they should have an ad blocker :)
