I was wondering the same thing. Turns out thermal pollution is a thing. They would heat a lake at that rate.
There are ways to cool water and recycle it. If they are using that much water, I bet they cannot cycle water because it wouldn't cool fast enough.
I've been using GrapheneOS for years and recently decided to try my phone's default Android. With stuff like this post and the Keep Android Open issue, I'll be going back to GrapheneOS.
