With the right reason I'll wholly support and encourage Mac use. Was one between 2009 and 2015, though I still have my Mac equipment it just doesn't get used. Over time, a little research, my own knowledge of electronic components and how they work, and observing the responses of those who just say "it's designed to run that way" (Yeah but not for the reasons they're trying to pawn off to people, the real reasons have more to do with poor QC, if not planned obsolescence.)
It all started with a certain benchmark comparison between the 15 and 17" models of the 2011 Macbook and how the 17" could perform better despite having identical processing chips and RAM (battery compensated for the woefully under-powered AC power supply, since the 17" model's was larger and yet the review site - a popular magazine - didn't figure it out.)
I also replaced an iMac with a Mac Pro of the era, for which I'm glad the warranty I bought was bought because overheating caused burn marks in the 27" screen. It's very poor engineering, contrary to those posh ads Apple put out with the "carved from a single block of blah blah blah". I later found out I was not the only person experiencing problems... or how many seem to have problems, either small or big, despite the constant claims of superior engineering...
Granted, when they replaced the 2010 Mac Pro, which was truly well built and had above average cooling mechanisms (I was applauding, big time) with that trash can for which various review sites pointed out how HOT the thing got under use (unlike previous models, due to its more compact form)... unfortunately, those review sites - typically known for going into detail - stopped doing temperature benchmarks. So I stopped going to their sites, if they're going to be lazy and not do the work, and other visitors of one site in particular was claiming the site was bought and paid for by Apple (I do believe they just stopped out of laziness, but if I went back and saw temperatures for any other products then I'd probably start to become curioius.)
What really frosted my goat was the revelation that an engineer told the Apple CEO of an antenna defect, which was ignored - thus explaining the real story, unlike the CEO screaming at customers how they were holding it wrong. No small or medium business, you know - the backbone of America's economy - would begin to get away with that sort of behavior, which customers did not deserve not just because they did nothing wrong, but since then it's been made well known what a jerk that CEO was. No ethics, character, principles, or other values (American or otherwise, maturity has no monopoly on a single nation). PC World, Bloomberg, Wired, and others all pointed out both the customer blaming (lying and blaming everyone else when knowing what's wrong is a sign of sociopathy according to the DSM) AND the engineer going to the CEO about the antenna defect (though apparently the manager was fired, but that still doesn't account for the CEO trying to blame the customers - truly a disrespectful act from a guy with a long history of being disrespectful as it turned out. He is not one to be worshipped, I'll save that for the real Christ.)
