This story seems to support the narrative that the US intelligence community is actively opposing the executive arm. While this might be a relief in some ways, it is profoundly worrisome in others.

The relief would be the idea that there is some effective reaction to the danger that Trump created when he was elected. He was actively supported by an unfriendly foreign power, and has spoken inexplicably praisingly of that power while at the same time being hostile to US allies and trading partners. The IC would have far more insight into this problem than anyone else, but are not supposed to reveal it. Recent leaks suggest that they have decided to act, plausibly in defense of their country.

The concerning part is the possible precedent. The CIA and NSA are not intended checks and balances on executive power, and if this is a deliberate act, it is an unaccountable one. However it might seem now, it could change if these acts continues under future presidents, that could could change.
