So? That's by design. The Senate was never meant to represent population proportionately. It was meant to ensure small states wouldn't get dominated by large states, and that means being able to block things. IIRC, that was a core compromise in the Constitution, and it's a bad look to go all Darth Vader on it (https://www.youtube.com/watch?v=jsW9MlYu31g).

It's a power play in absolute terms because the solution that's being pursued was chosen specifically to yield a partisan advantage. In some senses it's even worse than stuff like extreme Gerrymandering, because once implemented it will be almost impossible to undo or reevaluate. DC citizens could be also be granted federal government representation by making them citizens of Maryland. That would solve the core problem, and there's precedent: the government already did something similar to the part of DC on the Virginia side of the Potomac in 1847.
