The rules are decentralized and on the blockchain. This is also a disadvantage because rule can't be over-ridden to make an exception.
Another downside right now on dtube, I hope this doesn't scare you away because I'm big fan of steem and your channel:
tl;dr: Some % of the rewards from each video go to storage cost of the video itself. They plan to change this but as of now the rewards a video has gathered after 7 days determines the "guaranteed storage time".
"I have recently created the @dtube account. This account will be used to collect 25% of the DTube author rewards. 10% of these fees will be used to pay for long-term storage of the files on IPFS Store. The rate is $0.044 per GB per month. So, for example, let's say you upload a 100MB video, that earns $10 rewards, then $0.25 will go to @nannal and ensure data redundancy for ~57 months. Once this time is passed, users will need to either pay themselves (crypto accepted of course) to keep the files being seeded, or seed it themselves directly on their own PC and connection."
Though I think there could be possibilities to get around this.
Cheers,
