We have come in a very nice discussion over here. While the question at hand is a duplicate, OP raises a valid point:
It overwhelmingly affects Stack Overflow where I have plenty of rep points, yet the thread was moved to this site where I do not have enough to record a down-vote.
And that is true. The post was first placed on MSO, where a large amount of the SO users have the ability to vote up and down. Now the post is on MSE, there is a lot smaller group able to down-vote. The majority can only up-vote here. A regular user isn't able to express his disgreement with a down-vote now.
How would a regular user on SO, with little reputation here, express his disagreement with a network-wide change that affects the usage of that site a lot? (where the MIT discussion is just a sample) Should OP take it to Meta Stack Overflow and start a discussion there? Anything else?
