Indeed the communication factor is critical. I've been around long enough to see plenty of good tech fail simply because backers are not very good communicators and I think the top level comment is a great example of this. I am just a lowly end user, I just want to be able to install and run the latest version of PrusaSlicer or Zoom on whatever Linux distribution I am using. I don't obviously see how to do that with nix and I don't really want to spend the time to figure it out, while the folks behind flatpak seem to have made it a trivial experience.
