I mean, I wouldn't have a problem with that. I certainly never use named fiends from real world religions in my own games*, and I preferred the 2nd edition made up terms for demons and devils. The Satanic Panic was a misrepresentation of what D&D was, but at it's root was a religious grouping being offended by the use of beings they believe are real being trivialised as gaming pieces.
But there are no easy answers here. We have a responsibility as decent people to try and respect vulnerable groups, and pragmatism means it's a good idea to respect groups that wield real power. But also, we want to be able to do stuff and have fun.
And, of course, meanings and connotations change. "Phylactery" was fine until the connection was made to a real world religion, but once that connection was made it can't be unmade. The meaning has changed.
And, of course, WotC has made a number of pig-ignorant blunders over the years.
*I should say this is more a matter of personal taste, I know my players do not believe in any of those religions.
