I think it's more that there's a perception of things not being compatible with Linux nowadays. A lot of the games that didn't work 5 years ago now do, and I'm still seeing people complain that games like Halo Infinite don't work on there when they actually do.

The only things I can think of that aren't compatible and required for some tasks are Photoshop and professional CAD/CAE software. For >90% of the population Linux should be able to handle everything they need
