I can't answer your questions but have also made many thoughts about this topic lately.

We should not repel Steemit Inc yet, because this would cause a lot of turmoil and FUD.
Furthermore, Steemit Inc has invested money and time into the project and would be willing to continue doing so.
However, they should better integrate the community or give up responsibilities.

I'm sure we'll find a peaceful solution that everyone can benefit from.

I'm just not sure about their size of stake..
