I don't see how the two correlate - commercial, closed source software usually have teams of professionals behind them with a vested and shared interest in not shipping crap that will blow up in their customers' face. I don't think the motivations of "guy who vibe coded a shitty app in an afternoon" are the same.

And to answer you more directly, generally, in my professional world, I don't use closed source software often for security reasons, and when I do, it's from major players with oodles of more resources and capital expenditure than "some guy with a credit card paid for a gemini subscription."
