PPAs are not parts of the Trisquel project. For instance, you will not find
them if you browse http://packages.trisquel.info , whereas Debian's non-free
repository is proposed at http://packages.debian.org .
As you were told tens of times on this forum: there exist ethical ways to
make money with software (and if you cannot figure how, you can just work
with something else than software). Quidam (Trisquel main developer) is not
making a living from Trisquel yet but, hopefully, this will happen in a near
future.
Proposing proprietary software will never advance the cause of Free software
and, if nobody cares, we will soon end up with a GNU/Linux operating system
that is, ethically, as bad as Windows or Mac OS. Does Adobe's Flash spy on
you or open a backdoor to the system? Probably (who knows for sure but
Adobe?)...
Stallman's la-la land, as you call it, does exist. Trisquel is one of its
representatives. It exists thanks to the ethical (you wrongly wrote
"religious") concerns that has motivated (and still motivates) the
development of the GNU operating system. With your thinking, it would
certainly not exist and you would write "do not fault Microsoft/Apple, they
need to make money".
The same applies for drivers/firmwares: using non-free software will never
help us having freedom respecting hardware. Notice that rms' decision to
write a free operating system was taken after he was denied the access to the
source code of a printer driver.
I do not deny that the support of Wifi networking in 100% free distributions
is bad. As you wrote, it is "the sad reality". Anyway, the reality can be
changed (as the GNU project has done since 1984) and you do not need to be a
vendor to have some weight. As far as I know the "supply and demand" economic
model has always hold and consumers/citizens have other means to weight
(consumer associations, votes for candidates supporting free software, etc.).
Finally, and I write that for Mitja (I know t3g does not care), the operating
system should be called GNU/Linux and not only Linux (which is only a
kernel). More on that: https://www.gnu.org/gnu/why-gnu-linux.html
