A network service can raise issues of free vs nonfree software for its users through the client software needed to use it. If the service requires using a nonfree client program, use of the service requires ceding your freedom to that program. With many web services, the nonfree software is  JavaScript code silently installed in the user's browser. The GNU LibreJS program makes it easier to refuse to run this nonfree JavaScript code. But the issue of the client software is logically separate from the service as such.
