hi @ultratrain
It was a clear speech you have here
Steemit FAQ says
What are the valid reasons for downvoting?
Users are allowed to downvote for any reason that they want. There are many users in the community who recommend only using the downvote on posts that are abusive. It is up to you if you want to follow this etiquette.

Does a downvote mean that I did something wrong?
Just because you received a downvote does not mean that you did something wrong. The downvoting person may have just been voting to reallocate the rewards in a way that they felt was more beneficial to the other active posts in the platform. Often users will leave a comment explaining why they downvoted, but sometimes they might not. If they left a reason, it is up to you to determine if you did anything wrong, and if there is anything you want to change.
But unfortunately there is also an abuse of downvote from those who have a different agenda
