Honestly, best of luck and it would be amazing if you succeeded. Sadly I think actively supporting this requires a lot more faith in electoralism than I have.
I accepted after the Corbyn era that neither the Labour party nor the media care to actually hold politicians they like responsible for anything, including popular demand. Get 100k signatures and you’ll get what you always get, a lame excuse and then you’ll be ignored. Or even if Starmer came out today and said “Lying is okay”, would that stop a Labour win? I doubt it.
As a daily Fedora user, this is annoying. I totally support the push for open-source, but enabling RPM Fusion on new installs to do standard stuff is a royal pain in the butt that will immediately turn off new users.
