We may all have different ideologies and have different political beliefs, but the only thing that everyone agrees on and the only thing that everyone likes is money, and bitcoin gives everyone the opportunity to make some, so it does not matter whether you are a communist or a librettist, plus in our current society most of the people don't care about these kind of ideologies, for the late boomers and beyond who are the people that are shaping the future don't care about these stuff.
It's not true that everyone likes money, the ideology of communism seeks to abolish money totally, because money is in the core of market economy, and they want to replace market economy with communism, where everything is free. People like money only because it can be exchanged for goods and services, without it it's just paper or bits on a computer, so when money become worthless, no one likes them anymore.
So, communists wouldn't refuse if you'd offer them some free Bitcoin's, because a money is a money, but their goal is to make Bitcoin useless, and to them Bitcoin is a representation of pure capitalism, because it is essentially a digital private property, so don't expect communists to be fans of Bitcoin.
