I remember when Google did this for Maps. What a glorious day that was in the OpenStreetMap community. Big increase in "how do I host a tile server / geocoder" questions coming in.
Where would Bing API users move to, I wonder. How does it compare to Google pricing? Or ahrefs and petal, which are hitting my websites day and night? (Edit: tail -f access.log right now shows that ahrefs and petal are indeed going at it, no idea what products they offer though.) Yandex recently also upped its crawling game, has me wondering if they are making a copy of the web a la Internet Archive in case of more international, eh, operations.
