That's the job of each employee, CTO, and architects, together. Not the CEO. The CEO shouldn't make technical decisions like that.

Using your company's product isn't a technical decision. This is a ridiculous statement.

OTOH, I remember all the toxic managers (along with the HR, CEO, and other spineless people) who told me to chill out after having verbally abused people

Why are you verbally abusing people? That is not very nice. I agree that you should chill out and stop doing that.
