I forced every engineer to take sales calls and they rewrote our platform

I don't think this is an example of that. This is just engineers being able to talk directly to customers, which is great in most cases. I absolutely loved my jobs where I could directly talk to the users of our products, especially when they came to me with bugs or problems.

Unfortunately, that's not always possible. I wonder if that's why I always liked building tools for "internal" clients, other users within the org - it was trivial to just Slack someone or ask if I could walk over to their desk.
