I've been away for four days in a place with no internet access. I came back expecting to have missed lots of your videos - and there were only 2! Haha :)
I don't really think there should even be a conflict between Dtube and YouTube. Both offer different things. I used to make regular YouTubes until they changed the algorithms etc and it just didn't seem worth the time and effort, but I definitely will make YouTubes again in future. You say that there are too many "talking heads" on this platform and that producers aren't going beyond that level. I think that's because the videos are only monetised for 7 days, so unless you have a huge following there doesn't seem much point in making highly produced videos that take a long time to edit - unless you're going to post them on YouTube later for the passive income. The YouTubes I made a couple of years ago are starting to build in popularity now. I certainly didn't make them for the money - they haven't made me a cent, and they were more like therapy in a way! But in the long term they might actually earn me some passive income - how ironic!
I also make unmonetised "hobby" YouTubes occasionally. Who knows - one day I might try monetising those too. Why stick to one platform?
