Actually, it's not going to be a surprise for anyone once this happens (once again). Trump and Musk have already discouraged Bitcoin adoption in previous years. Trump didn't have a big impact, but Musk was responsible for causing a serious wave of pessimism regards Bitcoin when he stated Bitcoin was harmful for the environment, and therefore, Tesla was going to stop accepting it as payment method.
Instead of seeking for allies, I would search for friends. Real adopters, average citizens who are just trying to live their lives despite the tyrannical establishment not giving them any solid opportunities to thrive along the life, who have found in Bitcoin the gap they needed to reach a little further, against all expectations given by the system.
Trump probably had the start of a wakeup call when PayPal and Stripe cut him off in January 2021. One would think that having fascists like that disallowing you to accept payments would make one realize that having a censorship resistant currency, not to mention inflation protection and all the other benefits, would be smart to have available. I don't know if that makes Trump an ally, a friend or what, but smart people should see the benefits to themselves and the world itself when statist authoritarians are thwarted.
