Usually Apple only supports computer hardware for five years from the date the last model is sold. After this time the product becomes "Vintage" where in the past Apple would not repair it anymore unless you lived in CA (and possibly a few other regions where local laws made Apple support the hardware longer). Very recently Apple has begun allowing Service Providers the ability to repair "Vintage" computers as long as Apple still has the necessary part(s) in stock (this is a way for Apple to get rid of all the leftover parts instead of recycling them right away). If the part was available, then it would be a paid repair because the "secret" free repair program for the anti-reflective coating issue only applies to computers less than four years old.
Here is the Apple article about the "Vintage" status and what it means:
https://support.apple.com/en-us/HT201624
Vintage products are those that have not been sold for more than 5 and less than 7 years ago. Mac, iPhone, iPad, iPod, and Apple TV vintage products continue to receive hardware service from Apple service providers, including Apple Retail Stores, subject to availability of inventory, or as required by law.
For products purchased in France, see Statutory Warranties of Seller and Spare Parts.
Note: I added the bold underline highlights for emphasis.
