This is the sort of defeatist and way-too-easy attitude that turns things to garbage all around. In many ways, bringing up issues that affect many opinionated people's core values is how things get fixed. If this was said for everything that was free, then we wouldn't have anything.
For example:
"Linux has issues" "It's free. Nobody's forcing you to use it."
or
"FreeBSD has issues.." "It's Free. Nobody's forcing you to use it."
or
"I had a hard time installing Gentoo because of bad documentation. Somebody should fix that. No, seriously, metaland." "It's Free. Nobody's forcing you to use it."
I'm all for "beggars can't be choosers", but when there's nothing else to choose, of course people are going to complain.
