The parent comment poses a question: > If Adobe can't buy them, what other exit options do they have?

Operating as a sustainable business that sells a good product for a profit is apparently not even on people's radar.

I think they're responding to the question "If Adobe can't buy them, what other exit options do they have? Go public?". It's a bit tongue in cheek, but it's a fair point that we're in a weird place if the idea of founding a company with the goal of being sustainably profitable indefinitely rather than just being acquired by a much larger company is somehow the suboptimal backup plan rather than the main goal.
