Although still not without issue, my workflow has aligned so much with Linux and it's finally reached a good enough point for my day to day use... not having to use the VM based mac or windows docker has been really nice (WSL isn't good enough imho).
1) Other companies that are willing to sell you workstation and laptop computers that you can run other operating systems on such as one of the Linux variants, Windows, BSD etc. Nobody is forcing you to buy a computer from Apple.
2) There is a thriving second hand market of Apple machines just look at ebay, craigslist, gumtree etc.
If a new Apple machine isn't worth it to you, you are free to buy alternatives.
I am going to buy one of the newer Lenovo Thinkpads as I don't think the MacBook pro is worth it to replace my ageing Macbook Pro.
