After I updated PureOS, the Software Center suddenly started showing me packages from flatpak.org. There is proprietary software able to be installed with the click of a button. Examples include:
Sublime Text
Sublime Merge
GitKraken
It used to be that you had to explicitly enable flatpak repositories. Why has this default changed and why wasn't there any transparent communication about it?
P.S. Also AFAIK this goes against the FSF endorsement.
