No.
- MapQuest pulls its data from OpenStreetMap. If you check out the project DeFlock, you'll see how you can get involved if you want. (Or feel free to ask here.) That data isn't MapQuest's to "not share"; it's contributed by volunteers on OpenStreetMap who are boots on the ground working to document them.
- Proton is hosting a map using data taken from Flock in a data leak.
These are two separate datasets, where one (OSM) is unofficial, incomplete, and volunteer-made while another is the official data as of November 2025.
There are pros and cons to each, but what Proton is trying to fight is that Flock has sent a cease-and-desist to the person who published the leaked data.
