Amongst other things, people voting Sun directly or indirectly (in some cases through a proxy decision) doesn’t necessarily mean that they support centralization

I agree, but the end result is the same: it did lead to furthering the centralized control of the chain.

Same as a yes can mean no underlying

Up isn't down. Black isn't white. No matter how much context or nuance is added, but yes, I agree with your point that a "yes" is different than a "Yes, if I have to, but I really have strong disagreements which I'd like to explain..."

People shouldn’t entertain fears of discussing these things, cos these discussions and measure of freedom to react or interact is what leads on to decentralization.

Unfortunately I've been told to "shut up" and "leave" many times when I voice my perspectives. The fear is real for many.

No system is perfect, and we all know this. We're evolving governance as we go and mistakes will be made. One sign of effective governance is how well it handles mistakes. We shall see.
