Everything you said is highly plausible and potentially correct, but I think my previous post still applies. There's a lot of conjecture and motivated reasoning from all sides, enough that I'm doubtful that we can know what really happened.
Of course you're correct that Trump and Musk both hate Zelenskyy, and this established fact and not conjecture. Nonetheless it all still boils down to:
1. Musk has opinions
2. Trump has dangerously poor judgement
Yes, your statements are both correct.
My comment was more in regards to saying 'Musk has opinions' (who doesn't) is downplaying his involvement.
I'm basing this on what the 4 sources have stated mentioned in Telegraph article and also based on his previous behavior and comments about Zelenskyy / Ukraine and overall affinity and support for authoritarian political leaders.
It's all a game for him and winning at all costs.
