I’ve been a team lead and CTO, and when I was presented with some strategy or deliverable, it was my responsibility from that side of the table to speak from experience and point out banana skins and improvements.
There is really nothing personal at all in these interactions, it was just trying to deliver a better product as a team.
If you are putting forward bad work, or I am giving poor advice then the business has a performance management problem, but the to and fro of feedback is just a normal part of teamwork.
