CineStill are involved because they have the means to distribute product worldwide, and to provide internet store front and customer service resources.
Photo Systems doesn't so they hire CineStill to do it.
And the name change stuff is all tangled with what the bankruptcy of Sino Promise did to all the IP rights out there, so is frustrating, but understandable.
If there is a problem with the product, the best thing you can do for everyone is to bring it to the attention of the manufacturer and the retailer.
FWIW, at least early on, when I made enquiries using that contact form the response came quite promptly from CineStill, and it was clear that they were invested into bringing Photo Systems into the discussion.
As for whether brown Dektol like developer is a problem, I've successfully developed lots of prints in print developer of various consistencies. Brown developer may be less convenient, but not necessarily non-functioning. With print developer, it is relatively quick to check whether it still works properly, while you wait for replacement.
The other thing that can lead to brown print developer is damaged packaging that lets air and moisture in. Are their any signs of that?
