As a basic end-user I have not been too happy with my experience with flatpaks. I do appreciate that I can easily setup and start using it regardless of what distro I'm using. But based on standard usage using whatever default gui "app store" frontends that usually come with distros, it tends to be significantly slower than apt, for instance, and there seems to be connection problems to the repos pretty often as well.
An open-source, federated, and privacy-protecting alternative to the dominant advertising services. Something that gives the individual web user full control of which ads they see; from which indies, organizations, companies or any other groups. And where they can also filter ads based on clear categories, values, or tags, rather than everything being dictated by algorithms and "relevancy".
