This kind of opens up its own point: people need to accept that non-free software isn’t the devil. It actually can be really good for a community to have large entities investing real, actual USD dollars into it, and creating products and services that people want to pay for. It absolutely shouldn’t be the only option, FOSS is a beautiful thing and I love that the Unix community puts a huge emphasis on it. But, without some heavy hitters putting some money on the table, Linux/BSD will always be niche. They won’t go away, but they won’t blow up either.
My vote is always for plain ol Debian. If you don’t need a bleeding edge system, Debian will just work.
