The users were always the real service provider. All the value is in what they tell each other through their data. All Komoot does is aggregate it, supply the infra structure.

The only way to stop owners pulling the rug underneath all this community given content is by keeping the content open source. Promise the users you will do best with their data by keeping it out in the open so that if you don't, someone else will. Keep the door ajar.

Unfortunately this is another "if we all just" solution that humanity seems unable to do.
