This User Does Not Seem to be Happy With My Witness Votes

Two days ago I posted about using your witness votes, and I urged that hive users should also be using their witness votes and vote for the witness whom they see are adding value to Hive Blockchain.

This user ain't look to be happy with my witness votes, and for this reason he downvoted my post.

This is what he says.

According to him, I voted for top 30 and ignoring other guys that are below the list. But at the same time he is calling it centralization, because he wants a diverse group to be voted for and let these top ones die.

This user forgot that I voted for the witnesses because I think they are doing a good work by adding value to the blockchain. Yes of course I would like to vote for new ones whom I see are also adding value and doing a good job. They should definitely bring forward and tell the community about their work. @leofinance is sort of new compared to some others on top of the list, but I voted for them because they are doing a great job.

But why would someone want these top witnesses die if they are doing a good job for the hive blockchain?
