"Despite that, free software and terrible UI gets conflated"

I wonder why people would conflate those two things? Sure, not all free desktop software is bad, but enough of it is that people prefer the commercial alternatives.

So more people use free desktop software? Hmmm

Also, that is the most confusing statement I have ever read.
