How can anyone not want to use trisquel because it is not popular enough for
them.
There are advantages in belonging to a larger community. Better support for
instance. But why do you even care about the validity of the reasons someone
provides to justify her use of Debian or Trisquel? You are entitled find
those reasons stupid. But it is no justification for acting like the Spanish
inquisition, pointing out anyone that does not us free software for the same
reasons you do and saying (s)he is a "wuss".
The real reasons must be the same as every other free software advocate who
uses debian over trisquel. For prop drivers.
So, basically, you do not know but assumes that he is a liar. With no proof
whatsoever. If anything, buying a dongle that Linux-libre runs suggests
refusing proprietary drivers/firmware as much as possible.
The fact he uses debian and not trisquel, makes him fake enough as it is,
regardless if he uses prop drivers or not.
Where did he lie about using Trisquel when he was actually using Debian? You
are probably just making more things up...
