Yes, it is normal Emacs behaviour. See (info "(elisp) Invisible Text").

I guess we could clarify the manual. Suggestions welcome.

Yes, there is. Insert a zero width space after the opening brackets.

=[[xx]]= and ~[[xx]]= are not links; try to export them. 

However, `org-open-at-point' still treats them as such -- see last
paragraph in its docstring -- because this was a desirable feature for
some users, IIRC.

No, you cannot change link syntax, but you don't need to, either.
