I am really surprised at people still honestly believing it all started between Horner and a female employee and now "everyone" in the team wants him out because someone filed an internal complaint. It's completely irrelevant already, he was cleared of wrongdoing.
Public character assassination is neither the start, nor the end of anything, it's merely a step towards imposing pressure on subject at hand. With Jos leaking out inital details, the show started with an idea of forcing Horner out via public pressure, either directly or via Thais being forced to distance him from Red Bull brands. With Horner out, Mateschitz jr, CEO and Marko would like to take control over RBR and keep it away from Thais.
The only problem with all that is legal problem. DM had a carte blanche in his deal with Thais decades ago, but this does not transfer to Jr, nor does it transfer control over RBR to Jr. Thais have legal and moral right to do whatever they want with RBR, they can sell it or burn the whole facility down if they want. Of course they won't, but they do want a TP that answers to them as legal owners and execute their vision for the team.
Horner spent 20 years building this highly successful team and is nowhere near retirement. He's regarded as one the best TPs in F1 history, so why would he steer the team in wrong direction just because a new boss wants it? He wouldn't and new boss does not want him to, so we can rule this out.
I have no idea what kind of aspiration the other side has, but it was clear in Jeddah the conflict starts at the top. In any case, you can't preach peace and then start several fires to attempt an outright coup. I strongly suspected the state of 2026 PU is not satisfactory for Verstappen's team (whoever is there) and this is their right. What's not right is going behind TP's back to introduce special clauses to a contract. What is this TP now supposed to do, impose dictatorship and force everyone who is not loyal to him out? Right, that move has a very successful track record in F1
If you preach something, lead by example. It's that simple.
