You're complaining about broken updates on MacOS. I'm having trouble parsing your arguement seriously in the first place; people have been warning against auto-updates on Mac for years.
Given that nobody had anything taken from them, I legitimately don't see how you could demonize Valve over this. There is no way for me to sympathize with you over this, as a Steam user or as a former Mac user.
So now you're conflating intentional breaking software by deleting it and replacing it to avoid having to fairly compete on distribution like every other new game release... with auto updates.
Pro tip: using blatant strawman arguments to troll works better if you don't go so hard in the paint defending them. The latter just makes you look incompetent.
My entire point was to break down your conflation that users would "lose access" to CS:GO. That is wrong, and you have not produced any evidence to contradict that. My "strawman" is not an argument at all; it's genuine shock that anyone who cares this much about auto-updates would use a Mac in the first place.
I think you showed why I'm having trouble taking you seriously fairly succinctly.
