I have literally never downloaded pirated software since OS 9 went away and OS X became a thing. Open up your task manager and look at how many processes there are (Window, Mac or Linux) and ask yourself if you’re going to notice the one extra process that is out of place.
As for files with extra extensions, this is why you should always set Explorer/Finder/whatever to show all file extensions the very first thing, regardless of what OS you’re running too.
Toyota at least has an opt-out website. (Or at least in the US they do). You lose the ability to do stuff like remote start from your phone though. And emergency roadside service, blah blah blah. I turned off all the mapping saved route stuff immediately that let you see your previous trip average miles/KW and then turned off everything once they wanted me to pay a monthly fee for remote start and such.
