Let's say just like for example like MacOS. It's awesome we have so many tools but at the same time lack of some kind of standardization can seem like nothing works and you get overwhelmed. I'm asking for people that want to support Linux or not so tech-savy people.
More appealing? Linux runs basically all server infrastructure where even Microsoft bent the knee for Azure & Windows Subsystem for Linux. If we are talking about Desktop Linux, it will remain popular with those building software for easier/better dev tooling & wanting to better understand the systems their production code is run on. As software becomes more intergral to our lives & knowing how to write/debug it rises, folks will slowly keep trickling in as the have for decades where more & more software is treating Linux (& the web, & since BSDs, et al. are running similar software such as GTK they are also included) as a primary target. The other desktop OSs continue to shoot themselves in the foot injecting ads into the OS or denying system-level access to the machine you own.
A would say a better focus is mobile Linux… as casual users have migrated away from desktop OSs, where Android & iOS’s walls are holding them captive.
