@b0rk Adding to @karen's answer:
I have really tried to move on in #FreeSoftware culture (as much as I'm able) from the idea that computer users do something wrong by merely using proprietary software.
Just using proprietary software is not an affront to software freedom. Marketing proprietary software, getting users trapped into monthly licensing agreements, etc. are the bad acts, & if someone gets trapped in a proprietary agreement, we should help them, not berate them!
