What’s “blackmail”, especially given that these are aliens, and there is no understanding of their motive?
Understanding is not zero.
If someone expends resources in a way that has a good chance of influencing a person similar to you to do X, you can conclude that there is a good chance they want you to do X.
If this expenditure also harms you, then it may make sense to not do X.
