But, Minute Physics and Veritasium are on YouTube. So, maybe it's just cross-posting and their 99% audience is not there?
Of course from a "can I adopt X" perspective, cross-posted content to X is fine, even if most users watch it on YouTube.
But for that to be meaninful on a larger scale most popular content should be cross-posted to Odysee (or original to it).
E.g. Veritasium is for sure popular, but it might just be part of a tiny slither of YouTube content that made it to the platform - so that would mean I could adopt Odysee as a YouTube replacement only if my interests intersect with that slither.
