[Stoves] Balancing Technical and User Objectives

[lh cheng]

this article have bravery to face the truth and touch something somehow.

actually it is about humanity. someone in this area is hungry and greedy
for fame, money or power, they take action out of arrogance, they want to
manipulate and propagate to solve unexpected problem, and some of them lied
a lot, they are corrupted by the hope of money and fame. all this is
because some donation & gov money flow there.

I am not Nikhil, but I agree with him in many ways.

Let market solve this problem( market has the ability in this area ). less
money, but the gov or media can raise the attention about it, but no money
pls, There is dead flesh, there is flies.
