Ubuntu is doing stupid things with packages, replacing them with their proprietary packaging system (called Snap). It has been controversial, the way that they are pushing it, especially since the Snap server is proprietary and non-open source.
A lot of people won't consider using Ubuntu at all for this reason alone, and it makes sense - when you consider that there are so many other distros to choose from these days, Ubuntu just doesn't really provide a whole lot of added value anymore.
This would undoubtedly be wildly unethical, but those people should have been recorded and played back to anyone who refused vaccinations, for any disease really.
