There is always a reason.
Did you ask the person that was downvoting?
Did you research on your own before forming opinion?

Hive will be Steemit soon if this doesn’t change

So if downvotes didn't exist, it would be better?
How would you protect the reward pool? I am genuinely curious about your opinion.

P.S. Selfvoting all your comments with two accounts is probably not the best thing to do if you want to avoid the downvotes ;)
