I just stumbled upon this merge request for Krita:
It is about wacom like to merge code that tracks how you use Krita. They like to use this data to assure a painting is made by humans and not by AI.
It is related to the yuify service of wacom.
I don’t know if this is a kind of click bait merge request from somebody pretending to be from wacom or really wacom trying to extend its yuify user base.
Yuify was a talked about at some point in the past here. I remember it didn’t had a Krita integration back then (and I also remember I doubted that their service can actually do what it promised). It sounds plausible that Wacom now makes their move to add code to Krita to make their plug-in actually work after they also did with every other major drawing/painting application. I actually wondered if they would put in the work themselves and am kinda surprised that they did (on the other hand they have kind of a soft spot for open source). in this feature request I mentioned that Krita can’t integrate it because there is no documentation and Wacom apparently makes their own MR now, which sounds like the logical thing to do.
I only skimmed through the merge request and yes, it basically does what described although it does not send anything to anywhere by itself. That is probably what the plugin will do. It basically counts all the tool usages (most of them Krita does anyway because it is used for the undo/redo function) but also adds a few new actions and saves it inside the KRA file. It don’t see it tracking which brushes or filters you used only how often you used different actions, but as mentioned, I only skimmed through it.
I didn’t look at the plugin itself yet.
So the plugin itself is also nothing out of the ordinary. Basically a log-in, your stats and profile and a way to upload the image with the stats although I’m kinda surprised that it only uploads a png or jpg file and not the kra file with all the metadata. It uploads the metadata separately which you could simply fake (but could fake in the kra file too so probably no point in preventing it).
