I don't understand this given that we are fine with mentioning Windows
and macOS.

Is the below acceptable?

In comparison to the old page, it actively discourages using
distributions that GNU and/or FSF thinks are "non-free".  IOW, if I
agreed with your position, I think I would be more happy with it.  But
of course you would know better than me.

(The old page simply dodged the issue, which seems less than ideal.)
