Interesting take. It is valid and don't take my alternative interpretation as suggesting otherwise.
I owned a business for 18 years. For 15 of those years it was my primary source of income. I valued feedback, tried my hardest to solicit as much of it as possible, and always took it to heart (though I had to always try and glean statistics from the sum of all feedback so that I was never spending resources on minority opinions).
What I read from the user was that the company created an optics problem. It wasn't whether the company was losing money or not, it was just that the user is choosing to support that company because they want a really good search engine, and the optics of divesting the company's resources into multiple projects makes it appear as if it could be the case that not enough focus is being spent on what really matters to that user.
What I read from the founder was that the optics issue went completely over his head and a complete dismissal of the user's concerns and feedback, along with a doubling down of the decisions made.
It's not a good look in my opinion. Even though the founder was polite and didn't say anything inappropriate, I would NEVER have responded to a customer of mine like that.
