If you think about it in the end, DLive and DTube almost did the same and I mean that with no disrespect but the big difference is DTube just explained all the multiple reasons why it has to leave, DLive left quickly but for the same reasons DTube is leaving it's not the action that matters it's the reason behind the move that counts, in business if you don't move quick you risk losing it all if it's too late.
DLive had to leave because the business model was killing their platform and with the jerking around with SMT's that were suppose to be released a while ago, imagine they would've stayed? It would just be a full circle jerk of bidbots. No Famous content creator from another platform would've ever gave it a chance 100% under those circumstances.
DTube has to do the same as it needs to think about it's survival and future, @heimindanger is just doing what he needs to do, to keep his platform alive and growing and as you can see he's put in a great deal of effort trying to do that, but his efforts trying to help move steemit in a better direction obviously didn't work because of the odds stacked against him.
When platforms leaving becomes a trend it's time to stop pointing fingers at the platforms and it's time to look at the corruption and bad business models making this trend happen.
I hope everything goes well with your platform @heimindanger !
