Apple treating MacOS as if it's a mobile OS.
People don't use their macs like they use their iphones. People do actual, real work using actual, real software on their macs. If their plan is to turn MacOS into a locked-down kiddy pool of an OS like ipadOS then I'm out and I'd imagine many others would be too.
Absolutely inane decision made by people that have no idea how people actually use their products.
