As someone who now lives near a data center I can verify the noise sucks. Hell moved in next door.

The residents are stuck between a rock and a hard place:

Join the lawsuit and live with data center's unhealthy noise for years before an uncertain payout. Meanwhile their home's value is devastated because it's near a datacenter.

Or sell for the market value offer from xAI, which isn't great, and uproot themselves at their own expense. If only compensation and moving costs were included in the offer...
