When you say this, and after that…
…you say this. Then I’m in doubt. Rules are good or should be changed? Mathematical rules are the same thing as ethical rules. Decide what do you want and react in line with the decision. Consistency.
I agree 100% with the conclusion. I agree also with all your doubts, questions, and concerns. Let me clarify completely:
Envato gives a high value to ratings. How?
Simply, high rated items get prominent positions on the marketplace.
Customer’s point of view?
Home page prominent items, search page prominent items, category page prominent items based on high ratings. I forgot to add SEO and algorithm for advertising on organic search results by TF etc.
Authors point of view?
Now is struggling to keep high ratings. Why? Simply. Envato brings a new value to our ecosystem. The winning formula is: better rating = better exposure = better sales. Piece of cake to understand, correct?
When you met the author without the will to get a high rating at this moment he is completely dumb or simply does not care.
Stay tuned @charlie4282 and you will see. It has no sense to stay like it is now. With a new ecosystem of the values in combo with a locked possibility for authors to react on any ratings things must be changed.
Envato will remove prominent home page positions, tabs, and filters for the best-rated sorting. No, they will not. They will give more space for authors to react. Because Envato cares about the quality of the items they will realize that responding to any rating is a good direction for the higher quality marketplace. Simply like that.
But until Envato figure out what and when to implement changes I want my four-star without comment/content rating, from ghost customer, to be reconsidered. Not removed at any cost, of course. In my case, everything is so obvious that I feel pain from injustice when I think about it. Envato staff, buyers, and authors should work together to solve things, help each other. Why not? Because of the rules.
See you in the future @charlie4282! 
PS
Let me ask you @charlie4282 one rhetoric question. What you would like to see more when you choose an item to purchase:
- Ten or twenty 5 star ratings without the explained reason why they are left for an item.
- One 5 star rating with the minimum 255 chars explained why they think that 5 stars are deserved.
The answer is redundant. Because of that Envato will implement this solution, content is a must for a rating.
