Perhaps they simply don't know about it. OSM is doing its own thing and doesn't market itself much to the general audience. But for things that Google/Yandex are grabbing for free (opening hours, whether shops still exist, etc.), StreetComplete should be known much better, IMHO. It doesn't really help OSM that its home page is considered just an example of what can be done with the data and not positioning it as an alternative to Google/Bing Maps is somewhat intentional.
