Seems like a proprietary software endorsement. I guess it works also
with libre browser-based conferencing systems like BBB, nextcloud talk
or jitsi, so I'd remove proprietary from the description.

Yeah, I was also a little unsure about that part as well. I will remove
that from the description. Should have another patch to send in a
minute.
