There is a US Corporation behind Steemit...STEEM is not incorporated.

Where is D.Tube out of? Where is Zappl? Where is Appics? Where is Dsound? Where is Busy?

Simply because one interface is out of the US, that doesnt mean it will remain. In fact, bitshares.org just moved their operations out of the US to Thailand since the laws there are less restrictive for what they are trying to do.

Just the fact that there is a US corporation behind this project which is governed by US law does not give me much confidence in a sustainable future.

I am sorry that you feel that. It really sucks to not have hope for a sustainable future.

Fortunately, there are millions of people who do not agree with your assessment.
