See. You do not care about security.
Javascript runs on your computer. Not the server.
It uses your CPU, and it could be anything from one day to another. Just
because the it's coming from trisquel.info does not mean that it's from the
trisquel.info admins.
It can do anything (sandboxes can't shield you from intel's "cpu bugs", and
javascript can and does exploit them).
It's no surprise you accept the forced march to systemd and champion such
things. Aslong as it has the right license you do not care.
