For me the biggest thing is control, with Windows there are some things like updates that you have zero control over. It's the same issue with MacOS, you have more control than Windows but you're still at the whims of Apple's design choices every year when they decide to release a new OS update.
Linux, for all it's issues, give you absolute control over your system and as a developer I've found this one feature outweighs pretty much all the issues and negatives about the OS. Updates don't run unless I tell them to run, OS doesn't upgrade unless I tell it to. Even when it comes to bugs at least you have the power to fix them instead of waiting on an update hoping it will resolve that issue. Granted in reality I wait for updates to fix various small issues but for bigger ones that impact my workflow I will go through the trouble of fixing it.
I don't see regular users adopting Linux anytime soon but I'm quickly seeing adoption pickup among the more technical community. Previously only a subset of technical folks actually ran Linux because Windows/MacOS just worked but I see more and more of them jumping ship with how awful Windows and MacOS have become.
