Agreed. It is possible to keep the videos up by pinning them on your own ipfs server, but then you can just as well add them to a steemit post (at least link, embedding is probably also possible?) without giving 25% to dtube. The whole point of dtube is that they keep them up - but they only use 10% of the 25% you give to them to keep them up, so 2.5%... If a real big youtuber comes over here, thats sufficient to keep it up for quite a while, but otherwise...
