they started out as openstreetcam. they turned out to be not open, in source code and licensing of uploaded content. their app couldn’t even be open source, as it used closed source components (including facebook data mining components), that they did not want to remove. they have got renamed to kartaview and belong to a crappy company. they also don’t value user privacy, shown partly by using facebook (among other) tracking code both on the website and in the app.

at first, they turned out they don’t value privacy of its users, but with an openstreetmap adjacent project that is essential. most OSM editors and users are here partly for the privacy properties of the services and accompanying apps, and like that we can’t honestly recommend something to others that we ourselves wouldn’t use.

openstreetcam privacy policy said they share user data with third parties for analysis of the users. that alone shows how they treat their users, but their website contained facebook tracking technology among others, which is significantly worse for reasons I will not detail here.

in the openstreetmap ecosystem another thing that is important is openness and free software. because that’s how you can know how is your data handled, or how you can continue development if the original devs abandoned the project. all significant android osm apps are available on the F-droid store. F-droid vets all apps it accepts, including all updates to them, and closed source components are not allowed in any of them, because what they do can not be audited.
openstreetcam (at some point renamed to kartaview) was not willing to remove the unauditable components for f-droid inclusion. it was more important for them to collect enormous amounts of user data for facebook and other data brokers.

then the open source app completely stopped being open source. they did not officially stopped development, they just started to forget uploading the source code changes. they even tried to argue other points with “but our app is open source!” when it could not be built from source for several years already. that shows they only used open as a marketing term.

later it turned out the app was owned by a crappy company, and that they take all rights, irrevocable, for all images uploaded.

probably other things also happened I don’t remember now.
