100%! Often integrates better too.
I mostly mean from an advocate perspective, if a closed-source app developer doesnt want to build for Linux because the Linux desktop landscape is diverse and complex, you can tell them to just build a Flatpak and it will work and be installable everywhere.
That is a path of least resistance for developers which, I think, is leading to better app availability and compatibility for the Linux desktop.
I agree that some public discussion place for patches is an absolute necessity.
No idea what that would look like for the blogger though, maybe Lemmy isn't even that bad? You don't even need a Lemmy account to interact, he could use Mastodon to respond.
But yeah the overall vibe of the blog is very much luddite and boomer.
