English doesn't make sense because it's been influenced by so many other languages. I'm not sure of the etymology of Linux and Linus, but I would guess that they have different roots.
So, Linux is Linux because a set of events that lead to it being named after Linus.
It wasn't uncommon at this time for Unix systems to be named after their relevant creator or platform like this. HP-UX, PC-UX A/UX etc.
Linux would probably be seen as LIN-UX or LIN/UX, it may not seeing as Linux is not Unix, but that's just speculation.
Linux in its proper reading would be Linus Unix, but that doesn't make any sense Linux is Unix-like, but it was made in a vacuum without access to Unix source or even Unix systems at all near the beginning.
Back in like the mid/late-90s, there was a horribly compressed .wav going around the internet of what was supposedly a heavily accented Linus Torvalds saying “Helo my name is Linus Torcalds and I pronounce “Linux” as “Linux”, that’s “Linux”.
I know, because I’ve listened to that .wav a million times. And I still think he said “LEE^^uh -nux”.
