The thing is though, even though Sublime Text doesn't adhere to all Mac UI conventions, it does respect the most important ones and its appearance can be brought further inline with custom themes. Additionally, it's always performed excellently which makes up for shortcomings in overall "nativeness". This cannot be said for much if not most cross platform software that runs on macOS — much of it is strictly least common denominator when it comes to UI conventions, system integration, etc and more often than not is slow and bloated. I would say that the erosion started in earnest with Atom. People flocked to it because it was free (even though Sublime kinda was too, being nagware) despite its performance being horrendous and its lack of maclikeness, setting precedence for the acceptance of generic UI, sluggishness, and high resource consumption.
