I've made several Qt apps (in C++) easily packaged using AppImage. Perhaps OBS is harder because they require some level of integration with the hardware (e.g. the virtual camera perhaps requires something WRT drivers, I don't know), but in the general case of a Qt app doing "normal GUI stuff" and "normal user stuff" is a piece of cake. To overcome the glibc problem, it's true that it's recommended using an old distro, but it's not a must. Depends on what you want to support.
As a user, I prefer a native package, though (deb in my case).
Aaron was facing charges, and a really bad deal, and he took his life. He was never sentenced because there was no time for that, but it's obvious that things weren't going well for him, and that he was attacked disproportionally.
Meta is still facing investigation and will go to court still, and will very likely face charges for torrenting the data, same as Anthropic. They have not been sentenced because there was been no trial yet, it's still under investigation, because it will be a harsher penalty if it can be proved that they uploaded in addition to downloaded.
I think this is inaccurate enough to consider it misinformation (IMHO).
Yes, it is obvious that we all should fight Meta and praise Aaron Swartz. And it's true that the legal system is fucked up, and someone with power and money is in total advantage. But as despicable as Meta is, I don't think that saying wrong things is going to be the way to fight for our rights. There are already good enough arguments if we stay true to the facts.
