I am as upset as anyone else that Esteban Ocon probably won’t be racing in F1 next year. But this is not a good look for Toto Wolff. The other teams are perfectly entitled to hire whoever they want (particularly if a top-notch driver like Daniel Ricciardo becomes available).
If Toto Wolff thinks Esteban Ocon should be racing next year, he could always have given him a Mercedes drive. Notably, he hasn’t.
