Anyone who knows anything about IT knows that "Windows" is not "broken". It's just extremely "breakable".
The fact that a million ppl try to write viruses to steal money from the million banks that use it and have a billion customers that use it doesn't help either. But that's where professional security IT comes in. Not even a Mac is "immune" to this, so pro Mac IT should use security too.
The reason why carreers are made on "maintaining Windows" is because it's POWERFUL. Why would a group of engineers, developers, and MBA's constanty buy an OS that is > 3x more costly than a Mac OS...just up front? And require numerous certifications beyond a "CS degree" to upkeep? And this is just the "desktop" version, never mind the server version which is the leader in the server industry. No...it's NOT u/linix sorry...because "web page servers" are not the only computers in data centers!
The only "entire industry who grew up to uptake Windows" is the average person who tried to copy what they used for work...and in some cases, the software packages from "IT friends". They may be stuck with something they can't handle if they aren't careful about downloading porn, but it still doesn't change the fact that Windows is much more powerful and hence requires much more "computer-savviness" to use on average.
