I guess I need to get a Thinkpad running Linux for slowly finding replacments for my tools, and migrate not within weeks, but spreading my migration process over months.
My most essential tool is Emacs / Org and Lisp, Python plus the terminal with some shell scripting for automating all my workflows.
Yes, I will miss the smoothness that comes from very tight integration of hardware and services, but I absolutely hate the path that Apple is on, slowly taking all freedom from its users, until macOS is as closed as iOS. This is against every conviction I have as a citizen for whose freedom it is essential to have control over the machine that enables me to connect to the world and do my work. We are no toddlers, Apple does not need to put us in a walled garden, a promised land without any malware and danger (that‘s the promise, but in reality they want to control every aspect of their ecosystem, like an emperor that wants to tax every aspect of acting and movement in his land).
