"Oh, that path is actually not a temp directory and requires permissions different than the user account?" - sudo
"Oh your firewall blocks my outgoing telemetry data?" - sudo
"Oh your firewall blocks my localhost request but I don't actually realize that's what happens but when I try it with sudo it just works everywhere?" - sudo
There are myriad reasons apps want root access, and almost none of them are good reasons, but that doesn't mean it's not simpler for them to get sudo from a user than it is to get dev eyes addressing (let alone understanding) the nuance.
I'm not sure why I'm getting downvotes here... is there some cult of people who love installing apps with root privileges?
Or maybe the downvotes are because everything I was saying was conjecture / hypothetical anyway, and you're now asking a more specific question to the general question being answered.
I thought the question was "why do apps that don't need sudo request sudo?" And my answer was "perhaps because it's easier to fix permissions problems by getting permission for everything than it is to get them by understanding why your app is getting blocked by them in the first place." Whether it's inbound or outbound or taking video surreptitiously doesn't really answer the question of "why, if the app doesn't actually need it?"
At any rate, I don't actually know why because I don't ask for permissions that I don't need. I also don't know why you're getting downvotes as I didn't downvote you: this answer, like my previous one, is speculative, as is somewhat inevitable when trying to answer "why" questions that relate to the motivations of others.
Maybe more interestingly: I do think that the motivations of others are totally calculable. Society is an autocomplete. One big honkin LLM replete with all the hallucinations. Pretending to be a member of this society is to pretend that I wish to better understand why I'd be downvoted for a thought - to pretend that it's just me, a neuron, looking for back propagation. Yay for the neuron.
Nevermind, it's not important anyway. (Life).
