Same thing happened here, in Hungary, with ‘Kréta’. The open source app for it is ‘Filc Napló’. Kréta sued Filc Napló because of copyright and accessing to it’s api. So Filc Napló is kind of illegal 😄
Yes. I posted about it a while ago. But the app depends on crypto, so… People did not really like it.
