I think it was quite successful, and I doubt they are shuttering it because they don't see the value in it, but because of overall lackluster company performance and the new CEO cutting costs/the workforce aggressively.
This happened recently with Scitkit-Learn Intelex, which was a drop-in replacement for some parts of sklearn that was a bit faster. One day, the Intel channel on Conda just stopped working (and I learned that Anaconda loses the will to live when a random channel you installed one package from is unavailable) and another organization took over Sklearn Intelex.
No communication could be found on Google connecting them to Intel (whose only news around the package was announcing the initial release a few years ago), you had to read the Git issue history to find people talking about the transfer.
I still have no idea what even happened to their Conda channel after the sudden disappearance. The complete lack of communication just left a bad taste in my mouth...
But I have no idea who’s actually paying the bills, behind the scenes.
