There has been a discussion within LineageOS and they said they’re not anti-google so they’ll keep this check on google servers. They mentionned that they don’t have the infrastructure to face the connection of all LineageOS smartphones if they replaced the URL by one they own and I understand this.
In the other hand I’m sure google keeps track of the connections to these servers.
In the case of /e/ which aims at keeping our data to ourself and get rid of google, don’t you think it would be a good idea to change the URL? Or maybe to disable this by default?
