Boxcryptor used to be a one-time purchase to allow an unlimited number of cloud providers and devices.
However they decided they needed a consistent revenue stream so they renamed their software "Boxcryptor Classic", stopped updating it, and now users have to pay $48/year to get features previously available as a one-time fee. This was about 2 years ago, by now they've probably scrubbed all references to the "Classic" version on their website.
To be fair the subscription version does have new group/admin features for multiple users or businesses.
