I’m using BasicSync since a few weeks, the location permission is completely optional. This is what the app says:

Location permissions are optional and are only needed when restricting allowed Wi-Fi networks. Even if the permissions are granted, they will not be used unless there are allowed Wi-Fi networks configured.

It’s so ridiculous when corporations steal everyone’s work for their own profit, no one bats an eye but when a group of individuals do the same to make education and knowledge free for everyone it’s somehow illegal, unethical, immoral and what not.
