People who say "dee-mon" are probably 14-year-old Satanists in disguise.
If you want the etymology for it, "demon" is the modern spelling of what was essentially the same word. A lot of "ae" in Latin became "e" in English (prae- to pre-, encyclopaedia to encyclopedia). It was originally pronounced like "eye" and corresponds to αι in Greek. Phonological drift and Christianization caused the new spelling {demon) to imply something evil, so classicists in the 19th century resurrected the ancient Latin spelling with its original meaning: merely a spirit.
'oe' and 'ae' are pronounced /iː/ in English when they come from Latin roots. The same thing happened in Greek; 'αι' and 'ει' are both pronounced /iː/. It's only Americans who've fossilized 'ae' as /eɪː/.

It's not trolling if you just say "you are being trolled." At least put some effort into it, like implying we have wet dreams about Gosling or something.
The word daemon is an alternative spelling of demon,[3] and is pronounced /ˈdiːmən/ dee-mən. In the context of computer software, the original pronunciation /ˈdiːmən/ has drifted to /ˈdeɪmən/ day-mən for [b]some[b] speakers (read: autistic morons with oppositional defiance disorder)
