I'm not sure that's a distinction that makes a difference. If people didn't think OD&D was broken and needed fixing there'd never have been any other RPGs*. Again, that's literally how the entire hobby came to be. Someone played a game, thought something was broken, and got to fixing it. Fix enough things and it's a completely different game.
* You can trace this backwards in time as well. If Gygax didn't think Arneson's Blackmoor notes were broken and needed fixing, there'd be no OD&D. If Arneson didn't think Wesley's Braunstein was broken and needed fixing, there'd be no Blackmoor. Back to Strategos, back to free Kriegsspiel, back to rigid Kriegsspiel, etc.
