I didn't even see it as that. I saw it as perfectly rational behavior - you only need 10 minutes for a short standup, then squeezing it in between the tail end of meetings makes perfect sense.

Perhaps I'm a tad on the spectrum which is why I have zero problem with this, either from the perspective of the people who booked it for 50 mins or those who booked it for 10.

I did hem and haw over whether it was appropriate, but I eventually went with it because it felt in line with the first 2 sentences of the Wikipedia page defining the phrase as "Malicious compliance (also known as malicious obedience) is the behavior of strictly following the orders of a superior despite knowing that compliance with the orders will have an unintended or negative result. It usually implies following an order in such a way that ignores or otherwise undermines the order's intent, but follows it to the letter."
