To directly answer the question: within the last 3 or 6 months (I'm not sure precisely), they banned multiple youtubers that were placing ads to work for Russian Alabuga and it's drone production. It's an example of using their weight, in this case even something good.

On the other hand, I mostly actually agree with you. While I do think that they are picking their battles, I also think which battles they go into is usually not in your or mine interests. Instead, the battles are frequently in the interests of the richest google investors (think 10M+) and the US government, as of late. The Alabuga case above is a good and noteworthy exception.
