I suspect its popular in part, because it feels like fixing "the problem" without actually having to change your own behaviour at all. Don't need to change my gas guzzler, or fly less, or change your diet. I support the goal, but worry its a distraction.
Not sure if it is really a "movement" but it is the first glimmer of something that transcends D-R polarization. Like if any election is perceived to be a referendum on data centers, data centers lose, and it doesn't matter if it is red state or blue state or if the candidate presents as lefty or righty.
