Oh thank God, I was about to post something very similar. I have to reactions here, the first is the most charitable (but honestly feels like a huge stretch) and the other is what I believe.
Charitable: Perhaps the concern here is the use of private-sector tools rather than abuse of a government agency. I don't think that really makes sense, but it's at least possible. It would be a bizarrely naive take, even for The Guardian.
Realistic: The Guardian is a left-wing tabloid, and like much of the left-of-center media in the UK is obsessed with Israel for... reasons. Well I should say that their readership is at least, and the media provides. The Guardian is very much in it for the money, so if they can get "Trump" and "Israel" in the same headline as much as possible, they will make more money.
The Snowden revelations were over a decade ago, we know the capabilities the US Govt has, how is this even news?
