The idea that dTube was taking 25% of the total earnings of a post did turn off a lot of content creators but I understand why it was needed because it is not cheap to run servers that will host videos and it needs to be high speed.
I myself have used it just once since I am not a vlogger..
A lot of other vloggers though swear by dlive and I had recently uploaded a video through there as well and found it fast and they have a good curation team.
Yet I am happy that you took the time and effort to educate people and 11% is not bad and if they are giving back further with curation rewards then that is great news indeed.
The delegation though seems awfully similiar to what dmania did though so I am not sure how to react on that piece.
