They build good stuff and care.
Based on what I've read so far, with his shit-talking the competition, he seems like... a bit of an asshole.
Never heard of the guy before today, but his dickish, edge-lord aura (on X and in this thread) makes me not want to meet him. If I had to choose between buying from him, or some other random dude, I'll hear out the random dude first.
If you have such luxuries, I bet you don't have enough scale to be really profitable for him.
I can think of at least 4 other ways of scaling horizontally without switching DB engines. I'd have to be mightily constrained to have this particular product as the only option.

PS - Just some advice that I learned in sales 101 early in my career...focusing on shit talking the competition generally isn't a strategy that works well.

Only petty people can hold that view.
No one accused you of dishonesty.
