You're not bringing any arguments yourself. "There are no pros to using it" has got to be the most lazy thing I've read today.
Are we to assume that when the Google folks working on Kubernetes chose YAML they had a very brief moment of insanity? I can clearly see you hate it, but that's not an argument against it. Same for every other project that ever used YAML? Come on, that's a leap if I've ever seen one.
Those examples of yours are, again, very lazy. I'll take one of those just to prove my point: fossil fuels have bad consequences especially with overuse, but they of course had their pros, otherwise nobody would ever use it.
Take a deep breath mate. This is a discussion about YAML. Nobody is getting murdered.
