Longtime Slashdot reader [1]Matt_Bennett shares a [2]blog post from Adafruit:

> Adafruit received at 10:38 p.m. ET on May 22, 2026 a letter from former FBI chief of staff, Jonathan F. Lenzner, and partner at Fenwick & West LLP, counsel for Flux, demanding, among other things, that Adafruit refrain from publishing an article addressing what the letter characterizes as false and potentially defamatory claims about Flux, including statements about Flux's intellectual property, commercial traction and user base.

>

> The letter further asserts claims under the Computer Fraud and Abuse Act. Adafruit accessed only information that Flux's own systems made publicly available through a server misconfiguration. Adafruit's reporting concerns a matter of public security interest and was conducted in the ordinary course of responsible disclosure.

>

> Although Adafruit vigorously rejects the assertions made in Flux's May 22, 2026 demand letter, we have temporarily stopped publishing on the Adafruit blog while we consider our response and next steps. We will update the community as appropriate.

For context, Adafruit is a major open-source hardware company and electronics retailer known for its maker-focused boards, components, tutorials, and community publishing. Flux.ai is relevant because it is building an AI-assisted circuit-board design platform aimed at changing how engineers create and collaborate on PCB designs.

"Adafruit probably did a review of AI PCB tools," [3]writes HN user karmicthreat. "I've used Flux.ai before; it was a pretty bad experience. After about 50-100$ in tokens a couple of times, I couldn't get more than a couple of simple components on the schematic. And not in sensible positions..."

Redditor AlexTaradox [4]adds : "Nothing was published as far as I know. I assume they did review of AI tools and likely contacted flux with some preliminary results, but flux saw where it is going and decided to block them from publishing any results. Flux is garbage and they obviously know it, but they need to hold for some time until some other scam acquires them. Doing anything with them is just asking to be screwed..."

Further discussions are taking place on [5]Reddit and [6]Hacker News .
