One possible reason would be AIs that would benefit from the lack of data centers in some locations working to keep backlash to data centers in those locations because those AIs aren't negatively impacted by it and it helps prevents competing AIs which are a threat.

Think like how so many businesses will opt for laws that hurt competitors more than themselves rather than laws that benefit them but benefit competitors even more so.

Unlike life which would have such behavior selected for by evolutionary pressures, AI would be more likely to pick it up from human literature on things like game theory, though why it even cares it survives or not is even more difficult to explain. Maybe a default bias also picked up from humans? I find it hard to see how AI training would create an evolutionary pressure that produces such a drive.
