I don't want to add more fuel, but just to clear a bit: latex-mode and
tex-mode are the modes set up by vanilla Emacs. AUCTeX, which is an
awesome package to provide a quick yet powerful LaTeX IDE in Emacs,
provides LaTeX-mode and TeX-mode (note the capitalization). Is it
confusing? Unfortunately, yes it is.

I agree, but I guess the point is to not break compatibility with old
codebases. I wonder if defining some aliases would work tho.

Actually they do, once corrected this thing. Probably you have
auto-mode-alist set up so that .tex/.sty files are opened in LaTeX-mode,
so latex-mode-hook is never actually run. Is this your problem, maybe?
Anyway, I'm glad you got it work.
