I don't know if what I'll say will be off-topic here given that this
list is about Guix development, not on general free/libre software
activism, but please forgive me anyways.

So, my worry is that if we somehow were to support Fuchsia and if it
were to be not strong auto-upgradable copyleft with community-oriented
enforcement, then we could actually loose the freedoms of the software
for the end user. This thought was initially presented by Eben Moglen
during one of his talks[1], but I just tried to bring the issue to Guix.
