The company should have the ability to get rid of any witness they choose, at any time, just as they would have the ability to fire an employee. A witness should have no better status than any other employee...Witnesses are certainly not the gods that they think they are.
Alternatively, voting for Witnesses should take place on an annual basis, and all votes at that time should be accepted from currently active members only. As it now stands, there are Witnesses who have accumulated a massive number of votes, yet the vast majority of those votes are from members who have left Steemit long ago.
PS. I am not going to just keep answering your short questions, unless you are willing to contribute some additional dialog here, such as your views, etc.
So, the witnesses are not the company?
