Yes indeed. So why doesn't TBB include AdBlock? In my experience, unlike NoScript, AdBlock Plus rarely breaks sites. Reductions in site loading time are dramatic. And then there's the privacy benefit.
The reason given in the past by Tor Project leaders, was basically, they don't want Tor to be perceived as being unfriendly towards sites trying to make a bit of money to support their sites.

Some users don't disagree so much with sites presenting modest number of "non-intrusive" ads, but it's hard(er) to pick & choose which ads will be allowed, on which sites. Ad Block Plus makes an attempt at that w/ its hotly debated, opt out method of "allow some non-intrusive advertising."

I haven't seen the "browser fingerprint testing sites" being able to detect all addons installed, as standard practice. If java script is enabled, sites may be able to guess that specific addons are installed, by their actions - like preventing ads from loading. Even if JS isn't enabled, they might be able to see that ads aren't loaded & guess that ABP or something is installed. But detecting / guessing all addons - never heard that.

But if only 25% of TBB users have ABP & IF... sites (or adversaries) "guess" that it's installed by its action, then in their estimation, they've narrowed that particular browser characteristic down to 25% of TBB users.

If one lives in a free society & is doing nothing illegal under local laws, nor particularly interesting to internet tapping agencies, that might not be terribly important. On the other hand, what's legal or "not a concern" to LEAs today, could change in the future.
