The BBC doesn’t have a ‘CEO’ if you mean the Director General, there wasn’t one appointed in 2017. Tim Davie was appointed in 2020, with Matt Brittin appointed recently.
Possibly you mean David Clementi who was appointed in 2017 as Chair of the BBC, but he was a financier, with no background in journalism tabloids or otherwise, so not sure what you are talking about.
Laura Kuenssberg hasn’t been political editor since spring 2022. The political editor is Chris Mason.
I’m going to take the rest of your comments with a pinch salt.
