That's unexpected but its good news

There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community/
https://mapcomplete.org/ is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
Let's see where it goes. Many don't want to contribute to #Mapillary since they were bought by facebook.
But as #maproulette directly contributes to #openstreetmap, I can't see a problem here.
TomTom has been making a lot of challenges on MapRoulette for quite some time now, so if it's just bringing in money that's not too bad. I think the only way they can fuck it up will be to restrict challenge creation to TomTom employee, but since they haven't bought MapRoulette (yet) I don't see that happening now.
