If Debian could just stick to free software that'd be grand. It is a good ideology and there is no need to change it. Introducing ideological confusion is one of the paths to organisational rot.
Debian already doesn't just stick to free software. Let's say I have a program in debain's main repos. Suppose tomorrow I release a new version that uploads all your data (including shitcoin vallets ant passwords) to my server. All fully open source of course. Do you think Debian should include this update? Does rejecting it cause ideological confusion?
