In enterprise sales, there's often a huge disconnect between who you're selling to, and who is actually using the product.

In which context it might actually be perfectly correct to say that you aren't losing any sales over it, even if there are thousands of users who would use Linux support, were it there.

“We decided to go with <other vendor> because they have Linux support”

“The sales team says that's a requirement for the companies they're talking to”

“Competitor X has Linux support and they're growing faster with no other obvious explanation”

Most customers never contact your sales team in the first place if they see that you do not support their stuff.

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.

It's shorthand for, "We might be losing sales, but we assume they're a negligible amount of total potential revenue", which is a fair assumption to make.
