I see this said a lot and the Twins have zero control over what's happening here and when their contract is up, I suspect they're going to have some pretty harsh words to Bally over what has happened.
Remember, the Twins signed their television contract with an entirely different entity, Fox Sports. Bally bought Fox Sports several years later, well into the Twins contract, and that's when most of these shenanigans started happening. The Twins have little to no recourse to take action against Bally until their contract is up for renewal, which happens... after next season, maybe? It's not immediate but not that far away, either.
The Twins would love nothing more than for everyone in the area to be able to reasonably access their content. It's Bally that's doing this, not the Twins.
