There are advantages to using Tails for the use-cases Tails covers. You lose
anonymity by deviating software/hardware. So by using Tails you have a larger
pool of users to hide between compared running it on Trisquel and at best
being able to blend in with a handful of users.
There are other advantages as well. Tails includes firewall rules which
prevents accidental leaks. It's not a distribution you would want to use
all-the-time. It's overly restrictive by default to protect its users from
attackers. They aim to do things like security hardening, sandboxing, and
similar which protects users who really need anonymity. Not just people who
are trying to protect themselves from advertisers.
I do think removing non-free drivers from the distribution would be a good
move. However I think it might also hurt the ultimate real users who actually
need this software- as opposed to those of us who just want a little extra
anonymity- but don't have a government coming after us for saying the wrong
things.
If you do not need the level anonymity that Tails aims to provide Rubén has
attempted to add at least some support for Tor to Trisquel already. I'd be
more weary of it for anything more than more casual anonymity (like, if they
find out who you are your lifes not going to be over). Keep in mind that
Tails needs people also who are not doing anything that would attract
attention to. Without such users governments and the like can simply assume
all those using Tails/Tor/etc are people they need to watch out for.
