You called his inconsistency and at the very next post you named it "supporters leaving"..

I've talked with Mal in slack, and his questions are legit. He follows the project since he has invested in it. Do you see him shitting around 24/7 and being concerned about things in Lisk community, after he closed his positions?
He also tries to build a constructive criticism and to help the project (and his investment) in various ways. Basically not just finger point at what's wrong, but suggest alternatives and actively trying to improve things. Far better than being constantly concerned, wouldn't you agree?


I am still trying to figure out why would one be the most active "contributor" in a dedicated forum for months after selling all of his tokens.

You could use this time to walk your dogs more often - would be much better for them, for the community you are so concerned about, and perhaps even for you.
