I think they were referring to their own startup ideas. (I was also momentarily confused because "downgrade" tends to be used in the context of investments.)

I managed to put together an MVP of a service that would push notifications for stuff like "tell me when my favorite musicians/novelists/artists have new consumable," all the while thinking "if any of these people were smart they would have done this a decade ago." Of course Amazon started pushing out the book stuff, and Apple Music with music, just a few months after I got the back-end APIs working.
