I'm also not a fan of closed-source compilers (or fully closed, even worse), but it's unfair to disregard his work and opinions just because it's not publicly available.
Regardless of that, this is not a discussion about compilers or compiler design/programming, but rather about PL design, which are two different areas and disciplines.
