Well.. it's understandable that some people believe that things which are important and interesting to them (and presumably the ones which they work with on/with) are somehow inherently superior to what everyone else is doing.
And I understand that, to be fair I don't use MacOS that much these days besides when I need to work on my laptop. However.. most of those limitations are irrelevant/merely nuisances/outweighed by other considerations for a very high number of people who have built some very complicated and complex software (which has generated many billions in revenue) over the years. You're free to look down on those people since I don't really think they are bothered by that too much...
> for simple webdev it’s completely useable
I assume you also believe that any webdev (frontend anyway) is inherently simple and pretty much worhtless compared to the more "serious" stuff?
The main issue I have with it is that there are no problems in webdev any more, so you get the same thing in both the frontend and backend: people building frameworks, and tools/languages/etc. to be "better" than what we had before. But it's never better, it's just mildly more streamlined for the use-case that is most en vogue. All of the novel work is being done by programming language theorists and other academic circles (distributed systems, databases, ML, etc.).
Regardless, the world runs on Linux. If you want to do something novel, Linux will let you. Fork the kernel, edit it, recompile it, run it. Mess with all of the settings. Build and download all of the tools (there are many, and almost all built with Linux in mind). Experiment, have fun, break things, mess up. The world is your oyster. In contrast, OSX is a woodchip schoolyard playground where you can only do a few things that someone else has decided for you.
Now, if you want to glue things together, OSX is perfectly fine a tool compared to a Linux distro. The choice there is one of taste and values. Even Windows will work for CRUD. The environments are almost indistinguishable nowadays.
