Do you remember for ex the endless complaints that came from more or less prude, dishonest or honest or etcetctetc people, complaining about “offensive” mems, “offensive” profiles, “offensive” links links and what ever, appearing as such in the community created courses??? (I personally warned at the time about the nefarious results of such endless complaining).
as company trying to offer a product to small kiddies (from certain prude places) as well, I do bloody hell separate my main product and keep it free from such “offensive’” stuff, and leave the other site to the “adults in the room’”. And the liability for the adult stuff lies with the respective user and not the company, who does not dare to charge one for such “offensive” stuff. And such decision is pleasing to the ears of the “recent and greedy investor” who just gave 15 mill to memrise. A separate site and app for the in-house courses means complete control over the app and the site, finally.
The only point that remains in discussion is: what does the respective company earn from keeping up and improving such site and such app (Decks), and how does this company earn at least the costs to keep it runing? I do strongly suspect that the number of paying pro for community courses is not as big at it seems in here, and does not really bring too much profit.
Simple logic, yeah?
