You’ve used Windows for so long that you don’t remember how it was when you first started using it.
This isn’t different than what you are doing with Linux. The flow gets better and better and you will acquire the experience needed to navigate the issues. It takes time, that’s all.
If you stick to popular free software, the jank is limited.
The Linux userspaces have a lot of enthusiastic people that create their own software and share it, and thus it seems like there is lot of janky stuff (because there is).
It feels like Windows has been captured by corporations and so the market is competitive. There isn’t much space for enthusiast developpers to tackle a different vision of a popular software.
So yeah, I agree with you, lots of janky software in Linux, but that’s the beauty of it IMO. If you stick to popular softwares, the jank is somewhat equivalent to Windows.
