Google goes so far as to send businesses physical mail to make sure they put their business on the map. When an old employer of mine got this, I remember thinking of making flyers that people can distribute and drop in mailboxes for OSM.

(Similar to how my school emailed everyone, every year about how generously Microsoft gives us their Office suite for only 40 euros or something, failing to mention that LibreOffice works perfectly fine --if you don't mind the design-- and is of course completely free. Why not encourage people to donate 40 euros every 5 years to LibreOffice instead, or alongside?)

Didn't end up doing it, also because there just isn't an easy editor that businesses would use. I would make one, but then how would I make them aware of this? OSM in general and such an editor in particular? It's just such an uphill battle when everyone uses Google Search, businesses can get free advertising by putting themselves on Google Maps (that map shows up when you look for a local business or category of businesses), and Google spends a boatload of money on driving cars around and getting more business owners on board as well.
