Why are sellers not able to leave negative or neutral Feedback for buyers?

[amazing*2008]

One buyer win an item and did not pay, I sent her several messages, but  she did not respond. 7 days later, I canceled the sale.  Later, I went to the buyer's feedback and found that she had more than 10 of  seller's complaints which described her behavior as "never paid, never respond",  however,  the buyer's feedback is still positive.  How come eBay not allow seller to leave negative or neutral feedback?  So, what is the purpose of leaving feedback?

"Because the person with the most feedback in a transaction becomes the winner in a dispute . . ."?

Where do you get your information?

And BTW, the rule that states buyers cannot ever leave negative for buyers is by no means a new thing, but is at least 10 years old.  

Otherwise, I agree with your post.

I meant, if there was an issue, the person with 1000 feedbacks can leave a negative for the prrson with 10 and the person with 10 is highly impacted by that. The person with 1000 is not really impacted by 1 negative. It gave an unfair advantage and meant that whatever ebay said or did about issues, at the end, the petson with more feedback was the least impacted by a dispute and was more likely to win. Even if they lost the money end of the dispute, they would win the feedback war.

eBay clearly didn't do a good enough job spreading the word about the feedback change a decade ago.

I'm always confused when someone with an older account is surprised that buyers can't be left negatives or neutrals. I would understand a little more if the account had never had any activity over the past 10 years.
