I moved to Debian and then Ubuntu for personal reasons (first to get a newer
GNOME and then to get back to an Ubuntu base so I can use
SimpleScreenRecorder and OBS successfully), but I don't see any reason to
doubt that Trisquel is still a good and actively developed system. Of course
Ruben is busy working for the FSF, but the FSF uses Trisquel, so it's not
like Ruben is going to abandon it. Besides, has everyone forgotten how long
it took for both Trisquel 6 and Trisquel 7 to be released? Trisquel 6 was
released so late that Trisquel 5.5 was losing its support almost immediately
after, IIRC. In the case of Trisquel 7, it was much later than now two years
ago.
Also, to repeat, Ruben is not being paid by the FSF to work on Trisquel.
Trisquel is a side project for him.
Trisquel is still the system I would recommend to most people. It's fine to
prefer some other system; I don't like the bugs in the software versions
found in Trisquel 7, so I don't use it, and I probably won't switch to
trisquel 8 simply because I am knowledgeable enough to carefully use Ubuntu
and I don't like switching systems too often (it disrupts my workflow). But
Trisquel is still the best as far as distros to give to family members and
recommend to the general public go.
