Quoting Jonas Smedegaard <jo...@jones.dk>:
Software that requires signing a contract is "non-free by proxy" which in Debian means "contrib".
My assumption (which might be wrong, of course, and IANAL anyway) is, that both ToU and PP are only about their linphone SIP service, *not* about using the linphone program. Only the UI is buggy in that respect.
Software that tricks you into signing a contract despite not technically needed is non-free but might be easy to patch to become free.
Yes, somehow linphone tricks me into clicking "I agree", but I consider that to be an oversight by the UI designer/developer. But maybe you are right, and this really should be fixed for bookworm. Shouldn't be difficult to patch the UI accordingly. The software is GPL, so that change should be entirely legal. Cheers
