hi @mys
I strongly disagree with you on this. Nobody here has built their apps on somebody else money, we have built our Dapps without any help, with our own efforts, and our own money, and without expecting a delegation, since this was not something that you can count on.

"During years of delegated SP above dApps gathered more than enough to be sustainable. For free. Many many other Steem projects couldnt even dream of this possibility."

We invested our time and our money to develop those apps. So it's not totaly free as you say no?
When Dtube was first released it made a big boom in the cryptoworld and attracted a lot of users and potential investors to Steem... 3 years ago. Same for DrugWars, just to name few... In my opinion the delegation for Dtube at this time was even low compared to the value bringt to the chain... and for DW it has not received any, even while being the biggest Dapps in the world.

Why that? Did anyone of us put a barrier between other apps and Steemit inc? I never did this and supported all dapps who came to this platform. I did it personaly without expecting any profit and I can show you many proofs of my investment as a simple advisor for other projects. I'm always happy to give an hand to a new builder on Steem.
So again I disagree with you, if some apps wanted to obtain a delegation, they could have dreamed of it and probably received it too and this has nothing to do with the SBA and its delegations/apps.
