I'm not sure we should keep harping on water usage. Agriculture (especially in the american southwest) uses THE VAST MAJORITY of freshwater. Its not even close.
We should harp on the fact that they take up land, are loud, are being used for mass surveillance and state violence, and owned by billionaires. Thats reason enough to get rid of them. Oh and driving up electric bills (just got my letter this month telling me to conserve power becuase my bills going up. Theyre putting a data center here. Really pisses me off)
