It's made by volunteers so there is no guarantee of anything.
Something like Debian is surely more likely to keep going for years, possibly
decades from now because it has strong support from various companies, a very
large community and pool of users (relative to Trisquel) among academia and
software developers. It forms the basis of many distributions so probably is
most likely of all the distributions, along with Fedora and RHEL, to be
around for the next few decades. Ubuntu could die easily if Canonical went
bankrupt as it is basically snapshots of Debian unstable and a testbed for
Canonical's projects.
Point is, none of us have to use Trisquel. We choose to because we like the
community and want a distribution based on just free software, but we are, to
a certain extent, flailing in the dark, trying to find our way with
technology.
Yet we have the freedom to choose our path, and that's powerful. It's what
makes free software great.
Yet I totally see where you are coming from. We need more direct
participation in Trisquel's development. If not I might well pack up if
things get really slow due to what is essentially bureaucracy.
