"Could you be clear about what you mean by "political bias"?"
Sure. It's simple. Let's take Mark Dice (who I'll choose specifically because he makes fun of CNN who is clearly influencing the platforms now).
Virtually all of Mark Dice's videos are demonetized. Even though he is just exposing CNN's videos which are lies and poking fun at liberal thought. He really doesn't say much that is hateful or should violate any rules. And every Conservative voice that I watch has the same problem.
The Young Turks, however, are constantly and blatantly violating YouTube's written rules. And all of their videos are still monetized. It doesn't matter what they say, how racist it is, how inciting of violence against a group or individual it is, it's still monetized.
Actually, rural areas are a specific target of T-Mobile 5G. They can provide cell and home internet service together for nearly the same cost as only providing cell. A $150 bill (cell + 100 Mbps home internet) is much better than a $50 bill (cell only) when you are doing nearly the exact same thing.
