Adafruit halted new posts on its blog after receiving a demand letter late May. The letter arrived at 10:38 p.m. ET on May 22 and was signed by former FBI chief of staff Jonathan F. Lenzner, now a partner at Fenwick & West representing Flux.ai. It orders Adafruit to stop publishing an article that Flux claims contains false, potentially defamatory statements about its.

Flux alleges the piece cites its intellectual‑property claims, commercial traction and user base, all of which it says are inaccurate. The company also threatens action under the Computer Fraud and Abuse Act, arguing Adafruit accessed data exposed by a server misconfiguration on Flux’s systems. Adafruit counters that the information was publicly reachable and that its reporting serves a public‑security interest.

Adafruit’s press contact, Limor Fried, confirmed the blog pause while legal counsel reviews options. No court filing has appeared, and both parties retain the right to pursue further steps. The episode highlights tensions between open‑source hardware communities and AI startups over disclosure practices, reminding developers that misconfigured endpoints can trigger swift legal challenges for their organizations in the industry today.
