What is floatplane, never heard of it? Seemingly an yt competitor by a somewhat popular youtuber. App on Android has "10k+" installs. Isn't it _way_ too early to say it wouldn't be a money losing business?
My guess is that the commenter is either a Floatplane insider or possibly just optimistic :-)
Think of Floatplane as more of a Patreon competitor with a video component, than a YouTube competitor.
Linus' goal for Floatplane is "If it doesn't fly, it'll at least float." There's only 20 creators on it and it's intended to compliment YouTube, not replace it.
