how about they do what they want, and you do what you want, and you don't collaborate with each other if you can't get along? no reason to be angry.
if one of my hiring practices would reliably generate that many f-bombs, i'd consider it a success and stick with it!
Personally I judge hiring practices based on cost efficiency and quality of candidates, but I suppose "making people mad" could be an alternative criteria.
You're allowed to be angry when people do dumb things. Expecting your interviewees to install malware on their computer just to do an interview is dumb. Not only is it asking for trouble, it's also completely unnecessary. We have platforms specifically built for coding interviews, you just don't need to do that.
I guess, sure, companies are technically allowed to request you install malware on your computer. It's probably a CFAA violation, but nobody gives a rat's ass about the CFAA unless you're hacking the FBI, so who cares.
Also, make no mistake: a piece of software that is designed to record your screen, keypresses, etc is malware. It is spyware. You have absolutely zero guarantee it isn't install hooks into your system that will exist long after the application is gone.
Just do the interview in a browser sandbox like a normal person, and share your screen. Boom, problem solved, we figured this out 10 years ago. Really that paranoid about cheating? Then pay up and do an in-person interview, paper code test and all. I've had it done to me multiple times.
