Sounds like HTC is in denial as they don't want to admit there is a manufacturing problem. Alot of companies play the old BS of its the fault of the customer angle and most customers give in. But others persist and get what they want. HTC and Sprint are aware of the screen problem. You can either let then know that and persist or just pay the $35 which would probably give you less aggravation. It will be hard to prove that what they are saying is wrong as you are here and they are there. If the screen problem happens again it will be harder for HTC to play the its your fault excuse.
Don't forget to document everything via email and that you are aware of the manufacturing problems regarding the screen issues, etc. etc. and that you don't agree with the its your fault concept excuse or however you want to word it as long as you document everything and send them a copy. It will help for next time if there is a next time. You can post links in your email regarding others who are experiencing the same issue.
