Okay, but by that logic, if I can point to one instance of something suboptimal happening due to software being closed source, then it's reasonable to be wary of that too. I don't see how this is a plausible justification for keeping something closed source in the absence of taking into account the likelihood of something similar happening here, and for the reasons I laid out previously, I think it's borderline absurd to claim that was a real concern in the timeline that Mojo was closed.
People choose what to worry about. You can say it's unfair because they could've worried about a different set of things, but at the end of the day it's their choice.
I'm not saying you can't worry about this; I'm saying it does not seem to be a particular compelling reason for Mojo being closed source for so long, and I'm dubious that the rationale was due to anything like this.
