How the community has taken it

Reception is a sourced signal, not an editorial judgment: in litigation means the facility is or has been the subject of a lawsuit related to its siting, permitting, or operation.

Pending, U.S. District Court, E.D. Wisconsin (filed July 2026). Fairwater data center, 1.2 million sq ft, Mount Pleasant, Wisconsin. Village and county leadership are supportive; Midwest Environmental Advocates sued the city of Racine over withheld water-usage records, and Marquette Law School polling found ~70% of Wisconsinites believe data-center costs outweigh benefits. The Microsoft deal itself carries no new public borrowing, against a Foxconn-era backdrop of local debt.
