There’s basically nothing categorical that can’t run on Linux...
From a desktop standpoint, I agree. From a business server infrastructure standpoint, I disagree completely. We run tons of software that doesn't run on Linux. Maybe there are alternatives, but there are other aspects in play (integrations with other services, vendor pricing, etc).
It's not just desktops that people worry about.
I did see another report that it's just a component in Edge. Unfortunately I don't have that link handy right now.
