According to the post, Steam support concluded the controller would need to be replaced to fix the user's problem. The reply acknowledged that the warranty on the purchase had expired, but offered a replacement anyway as a customer service gesture.

Support then asked the user for their full name and shipping address so the replacement could be sent.

The post shows Steam agreeing to a replacement and asking for shipping details; it does not confirm the replacement was sent or received. It also does not say which controller was involved, how long the user had owned it, or what the fault was. It is a single user's account, and nothing in it suggests Valve has changed its warranty terms. Whether support makes the same offer in other cases is not established.
