Anyway, I think it's weird that Google employees will react like this over the sale of a service. In it self GCP is pretty harmless and its sold to a democratic government. It's also the Israel government, not just the IDF, so most of the services would presumably be used for peaceful purposes. At the same time these employees are apparently completely fine with Googles invasion of peoples privacy, manipulation, sale of data to shady advertisers with little oversight, collaboration with the US military, collaboration with China and a number of other issues... But no, this is apparently where Google crosses the line.
If Google employees where constantly applying internal pressure to management and shareholders to do better it would make more sense, but right now it seems pretty random.
