Unfortunately, Sailfish OS uses a proprietary (closed source) android compatibility layer, as well as a closed source UI.
For the parts they have open-sourced, they implementrd a CLA that contributers must sign. It’s the HA-CLA-I-ANY license, which specifically allows them a perpetual Copyright and Patent license, and permission to relicense your code contributions to a more restrictive license which enables them sell or package it into a closed-source proprietary app.
Personally I’d be more comfortable supporting the development of PostmarketOS instead, since it is completely open-source with no CLA, meaning no chance of any rug-pulling in the future.




















Please consider donating to PostmarketOS to build up a pure mobile Linux alternative that is completely free of Google’s influence. It’s the best option we have.
