Maybe I am misunderstanding the summary, but it says: "If you publicly use any adapted version of this database, or works produced from an adapted database, you must also offer that adapted database under the ODbL." <https://opendatacommons.org/licenses/odbl/summary/>
For example, if I use Google Maps to drive to a new neighborhood and then take a bunch of notes about the new neighborhood, my notes are not subject to the terms and conditions of Google Maps.
If only. Maps are still super broken around where I live. I personally mapped everything in OSM (which thankfully is used by most third party services these days) a couple years ago, but Maps is still people's primary source for routing and traffic related stuff.
It gives hope that Google/ESRI won't always be the dominant mapping platform, however OSM is still missing a lot of local businesses which the delivery platforms don't need as urgently as house numbers so there's less focus there.
Are they? I get the impression that only consumer-facing stuff is Google, to give people a familiar color scheme¹ as well as allow terribly formatted search queries to still work (if google can do one thing it's search). However, anything using geo data in a back-end fashion seems about evenly split between government base maps, OpenStreetMap, and a collection of misc providers that Google is one of
¹ conversely, I struggle to find my home town on Google Maps. It's all about vague, washed-out shapes, besides the bright shop icons and, nowadays, advertising pins. It's a matter of what you're used to so I can very much understand that the average consumer, who's less familiar with maps than me, is totally lost when getting Carto as a map

It's more surprising at this point that Google isn't getting in on the fun, at least taking the good bits and calling their own data a 'separate layer' so they don't have to contribute anything back. (And of course no Chinese companies, since accurate maps are illegal there: https://en.wikipedia.org/wiki/Restrictions_on_geographic_dat...)
Where it's lacking is business info since this has to be entered manually and changes much more often than streets or buildings change.
This kind of cheating usually works extremely well, from my observation.
Anyhow, Google owns Waze and data goes back and forth between there and Google Maps. They're like two heads of the same snake, so it's implicit that the same thing also works on Google Maps.

No way they are doing this deliberately globally. My city has a lot of pedestrian stairs interconnecting roads, and not a single one is on GMaps. If you navigate on foot, it will send you on walks 2x-3x longer than necessary.
OSMand and CoMaps reliably find the shortest way. And can tell you the pavement type, number of steps, stroller ramp and hand rail situation of every single one of those stairs.
Google has a really hard time adding roads without frequent car traffic, I think.
