I completely agree with this.

At a few of the start ups I've worked at, "no" wasn't in the dictionary.

It was always a dumpster fire, the product had some many configurations and options. There were entire sections of the apps I didn't know existed. I think that all these features are ultimately what killed the start up.

At one point I (developer) had to go on a call with a customer to tell them no because the PM didn't want to disappoint the customer.

Learning to say no is extremely important for startups.
