If you're designing a car, then the CEO/Founder might want the ability to add falcon wings to it at any point, and that's pretty reasonable. If you're designing a trustworthy encyclopedia, knowing that the CEO/Founder might wish to alter arbitrary facts to his whim is really not very reasonable. Is it his company? Sure. Do you want to make low-quality information artifacts? That's a judgement call.

What? I work for a different frontier lab now, and it absolutely would be ridiculous if they told me the same thing. Luckily they haven't.

What products have you worked on where this would be deemed normal?

Sounds pretty crazy to me, bud. I keep landing on 'servitude with extra steps'. Owner should have better things to do/people to bother, I should have space. Boundaries, etc. Yeah yeah, I'll never make a bazillion dollars. I'll know freedom.

Even an executive assistant, which I would never apply for, has off hours.
