It's easy to take a stab at someone online, behind a keyboard, but I'd suggest you show us all your work and we'll judge your future opinions based on it.
By no metric I am comparatively as successful as the guy, but I am still able to disagree on his point that Linux is held back by its tools. The fact that he did not want or had the time to learn Linux's tooling don't mean anything in particular except that he's either very busy or very lazy. Any interview I read with him he's just ranting and crying over this or that "too complex" matter.
If he does not want to deal with the complexity of modern computers, he should design and build board games.
