$300 as an argument as to why this software is supposedly worth more doesn't really stand.
I mean most people are fine with iMovie. Fact.
It is not the price tag, it is the fact that one owns it that matters. Just like DaVinci Resolve. Renting software creates lots of issues, and Adobe’s update “process” is a nightmare for those of us who have to manage longer duration projects.
Any reasonable managed business that makes money eats the yearly $599 like it didn't even happen because it is literally a no issue. Add photoshop, ilustrator, indesign and tons more into this bucket and all of a sudden that doesn't look like much. Hell, quite cheap really that's if you actually use it to make money not memes.
On top of that you have access to a PC environment which is very scalable and can be managed / upgraded with a flick of a finger quite often for cheap.
People like you amuse me. On one hand you argue that no one should care about spending $600 a year, for something that ones uses to make money, but on the other you argue that buying hardware that does not lasts longer and needs less management support is too expensive. None of the studios nor professional shops with whom I work, upgrade individual components. Not worth the time, downtime, cost and related instability (true for both Macs and non-macOS intel systems).
