Most people don't:
* think it will impact them.
* have any idea what to do about it when the most powerful
person in the country can do literally whatever they want
with little to no pushback."President is the main person end has exceptional power". That's the mental model for most people. There is no any internal conflict with law violation and any space for reflection what's wrong with it.
They could start with:
1) Peaceful protest, and
2) Boycotting anything related to Musk, Trump and anyone that bends a knee. (When that's literally impossible, as in "I have to buy food somewhere", pick the least bad)
Simple, but inconvenient. Better to make excuses and hope someone else fixes the problem at no cost to me.
I don't have the energy or time to join protests. I donate substantially enough that it's noticeable in my finances to Planned Parenthood, the ACLU, Fair Fight, and a handful of others. Tell me I'm not doing enough, that's fair. Tell me I'm doing nothing, and that's a little insulting.
