Fascists? Virtually the entire house of commons voted them a terrorist organisation, not just Labour. That was because they attacked UK military aircraft on a UK military base and concocted an excuse for doing it. That got them branded terrorists.
This does not in any way stop people rallying for Palestine or the appalling inhuman injustices they’re suffering. I’m sure there are marches happening all the time, not to mention charities to donate to, social media feeds to amplify atrocities. Just don’t attack UK bases or support those who do and you’ll be fine.
As for Corbyn, he wasn’t “stabbed in the back”. He lost two general elections in a row and he resigned. If he was still there for the last election he’d be sitting in opposition in charge of an even smaller party surrounded by a clique. He was not some saviour for Labour, he was the bane of it.
While I wouldn’t want flakpak going deep into the OS I think the advantage of using them on the desktop is obvious. Developers can release to multiple dists from a single build and end users get updates and versions immediately rather than waiting for the dist to update its packages. Plus the ability to lock the software down with sandboxes.
The tradeoff is disk consumption but it’s not really that big of a deal. Flatpaks are layered so apps can share dependencies. e.g. if the app is GNOME it can share the GNOME runtime with other apps and doesn’t need to ship with its own.
