Is this a uniquely Amerian debate? I live outside America, and I don't really understand the subtext of these Coinbase posts.

What does are some concrete examples of a company being political or apolitical? What are the kinds of things the Coinbase used to do and no longer does, which employees might leave over? Is it about the company donating to political compaigns, or openly participating in community debates and having a position on social issues (same sex marriage, abortion, Black Lives Matter, Trump, gun control, etc)?
