To be honest... these dapps had delegation for far too long. I see it as a startup bonus... Here have a delegation for 6 months prove us that you are doing something with vision, and gather your own audience. Simply because you have a dapp does not give you rights to have million steem delegations.If you are good enough you will find supporters and start build dapp and community around it even without delegation.

Fundition has misused funds for so long, no one addressed this and they have 0 users on their platform (state of the dapps metrics).

Steemhunt had interesting vision and project - never went deeply into it and apparently has the most users on them all. can't comment anything on that.

Steempress is a nice implementation but so far for being present for 1.5/2 years to only have 20-100 users in 24hours - does that require 1million delegation to go on?

There were numerous talks about dtube and their policy... the I don't care about steem and whatever happens, has been voiced by dtube few times. Why would you support them more? Yet they still have significant chunk of steem delegated.

3speak got their own 1mil... nothing to worry about that - was never delegated in the first place, not sure why it is listed there - might be developed by oracle-D but there there is SPS for development not a delegation...

And oracle-d has also been around for about 2 years - the most supported thing is a football school academy - which their last post was 5 months ago. And the promise of bringing whales and write posts for them... I don't know
