I would argue that if brew is installed on a Mac, chances are, OP won't even notice it's Mac OS, unless he looks into the detail or having some specific Linux use case. OP only mentioned writing some C programs.
I don't make my bed too, but I swear there is some psychological/ritual shit going on in there. Another example would be why go to the church. Can't we just pray and confess on our own balcony?
Why hang up Christmas lights only to take them down a week later?
Why read when (if) we can inject knowledge into our brain?
Why workout when we can just inject steroids?
Some of there stuff are more of a waste of time than others, and I suspect it is the reason OP has this (un)popular opinion.
Point is (again), it takes zero effort to cross post a video or article here. Windows is historically having a high market share ratio, and people are migrating to Linux nowadays. That's good news to the Linux world. Even someone merely mentioning ditching Windows has an implication of adopting Linux instead.
But what if more and more posts implying this by only mentioning how bad Windows is? Is this a community for Windows circlejerk, or do we share informative stuff that's directly related to Linux? How about we share more article about how great Linux is (or can be), instead of how bad the competitors are becoming?
What's wrong with going back to pen and (e-)paper for office? My point is, if you are going to post something in the community, the word "linux" shall at least be in the title.
Good title example: Europe is slowly ditching Microsoft for Linux
It's nobody's fucking business when someone ditching Microsoft, then adopt BSD, Solaris whatnot. What matters to this community is someone adopting or ditching Linux, or they do something remotely related to it.
Why does every one need to compare every distro to NixOS? We get it. It's neat. It's immutable. It's indestructible. But they are fundamentally different stuffs.
They would have way higher ratio of supporters if they stayed at XP or 7, and just keep security patching it but no, they deliberately sabotaged their star product with Vista, 8, 10, and 11. They deserved it.
Since OP uses it for freelance business, self-hosting and stuff, I recommend even one step further, by a new computer and try to replicate all workflows there. Don't fuck with the old one until one day OP suddenly noticed that he hasn't booted his old computer for one year, then he can sell it as parts.
What are you talking about? This guy dies and comes back alive every time!
