I don’t reply to most comments. You should see my inbox, I have hundreds of undealt with notifications. I only even spotted this reply because I was correcting an autocorrect mistake on my previous one.
My numbers were correct and I explained why.
And your experience is pretty far from mine, I had to give up on appimages because they are problematic by design.
And like I said, Flatpak hasn’t been bad on storage for me. It uses deduplication and unlike you I didn’t go out of my way to cherrypick a small handful of applications that just so happened to use three different runtimes in order to bash it.
Use appimages if that’s what you want, but they’re not really an answer to Flatpaks, due to the huge systematic problems they have.
