Lawful is meaningless in the context of the Trump administration. Should Google waver (which they won't), they'll be declared a supply chain risk or otherwise bullied into submission.
Google holds immense power in their position. Trump can make their life very difficult but Google can make life for Trump very difficult as well. They have no need to kneel, they are choosing to.
Google simply cannot justify this power struggle, it can doesn't mean it will. It got to the top by kissing the ring and that's how they stay at the top.
I still disagree with your point Google having enough power to supersede the democratic process. If they have "good will" and fight back, someone else will take their place.
You don't think Google having control over the most used email, most used browser, most used search engine, most used video website, and most used phone OS gives them immense power?
