I like Guenther but he's not a good boss, threatening to sack people at the drop of a hat does not foster a good working environment. Apart from that he's a cool guy, but not the worst team principal on the grid.
Clair Williams is not the right person for the job of turning Williams around. She's had long enough and all that's happened is that they've gone backwards, and they still look like the slowest team this year. She would be an ok section manager, she like's details, like getting the teams kit sorted, or making sure people are wearing the right kit at the right time(she actually did this).
She doesn't have much of a clue with regarding details on the car, but she hasn't got the right people in place to take those responsibilities off of her. She needs a vehicle performance manager, like Andreas Seidl, to take load and let her deal with the finer details of running the team as a whole.
Paddy Lowe fell on his sword for the team, he had to restructure the team AND be responsible for the car - that's too much for anyone. Whilst I don't rate Paddy that highly, he isn't responsible for the crap-fest that is Williams at the moment. It didn't help that the car was very bad, worse than the bad car of a year earlier, so I do agree that he had to go, it just gave Clair an out as to who was responsible - ultimately it's HER.
They will have to get rid of her soon, I'd say it'll happen during 2021 after the new(rules) car is bad also, how many chances does someone get? She will run Williams into the ground, she doesn't even see it.
