I mean, I understand that, it's the same reason for the "universal translator" conceit, so you don't force people to read subtitles and all that. It's how casually and universally that the Orville uses it that I find jarring when it happens. A dick joke doesn't nudge my suspension of disbelief, but a crack that references a TV show does.
I mean, dick jokes are universal. The oldest (known) joke in British history dates back 1000 years, and it's a dick joke ("what hangs at a man's thigh and wants to poke the hole it's often poked before? A key"). Pop culture references aren't, though. Try reading Gulliver's Travels sometime, and figure out the satirical references, without using a guide or a history refresher/textbook. Gulliver's Travels is a piece of classic literature, and the satirical elements are incredibly obtuse if you didn't live around the time it was published.
I know why they do it, but it kicks my suspension of disbelief in the pants every time they do.
