Flux just got funding from Bain and others, and it feels like Adafruit was preparing a post about it. Maybe they contacted Flux to confirm some info and they freaked out?

I can't find in archive.org if they had a previous post about it.

Also, seems like there a good bunch of complains in Reddit about Flux and its billing...
