I am not sure that killing a character whose death will have a major effect on another character is necessarily a fridging. I do not think, for instance, that Aunt May was fridged in No Way Home; at least insofar as Uncle Ben would not be considered to have been fridged. However, that said, I think you could certainly make the case that Uncle Hector was fridged. Was Foggy fridged? If he was, does the term lose meaning as every important death turns into a fridging?
Fridging is one of those things you look at in the aggregate rather than on an individual basis. The idea behind fridging is female supporting characters in comics very often suffered disproportionate harm relative to male supporting characters. You can't just look at one instance and say, "That's not fridging," because it's a trend not a one off event. Which kind of makes it difficult to critique of course because we can't just sit here and say "uh, huh," or "uh, nah" at ever instance.
Me personally, I don't care if a supporting character is killed to advance the plot of the main character. Supporting characters exist to advance the plot of the main character. It's why they're called supporting characters. But if female characters are disproportionately harmed compared to comparable male characters I can see why that might be a problem. And for the purpose of this discussion I'm just going to assume it's true.
