This very much depends on the product but note that is exactly why I listed other possibilities. If Linux support was a big opportunity they’d know — maybe not precisely but enough to know it was hurting them.

I’ve been using Linux for around 25 years, some of that selling commercial software and most buying. There’s a very noisy contingent of the community who make a lot of noise but never actually buy anything. You’ll go broke chasing their feature requests because there’s always one more thing before they can switch.
