    i THINK they’re saying that they sublicense a library to do encryption in order to talk to WhatsApp and that it’s this software that they won’t be allowed to be included in GPL-licensed software because it may be that in the future that implies a release of source code?

    this doesn’t seem unreasonable as long as you can create a facade or abstraction that’s NOT GPL-licensed to interact with WhatsApp that then interacts with your GPL code?

    or i could be misreading entirely
