They stopped shipping these latest adapters nine years ago. I think their obligation to replace these for you gratis ended a while back. Did you expect these to last your entire lifetime? If you don't want to get the free new replacement, then don't. You don't "have to" go through this if you don't want.
Don't understand the "attitude" in the response. I happen to own one of the impacted adapters. I did not expect mine to last a lifetime, but they still function. These units are being voluntarily recalled by Apple and I have been contacted by them twice in the last few weeks, so they are reaching out to us. If they offer a program, it should be easy to replace them. Finding out it is not so easy sometimes (which I found out too) should be neutral subject one can post. Your mileage may when handling the recall. Recalls are normally gratis though, whether government compulsory or company voluntary. A recall is often far cheaper than a lawsuit with a significant damages / treble damages claim.

The chargers may be in use even if the original devices are not.
I'm typing this on my 2010 MacBook Pro 17 which is still functioning just fine. I got the power adapter kit to travel to the UK and Europe. Still functions many years later.
[doublepost=1557263989][/doublepost]I wanted to share my experience with recall since experiences can vary.
These power adapters are being voluntarily recalled by Apple, and I have been contacted by them twice in the last few weeks. First time I gave the Adapter Kit box and copy to the email to my brother who lives close to an Apple Store. I do not. The store would not replace it since the email was not to my brother, but he had the entire adapter kit with the recalled item and email with him. If safety is important, replace the impacted adapter rather than argue who is holding it in their hands and sending them away.
So later I get another email on the recall. Since plan a above did not work, I tried to setup a call. The website requires a serial number, and the World Adapter does not have serial number. I entered the serial number of my laptop, which is a 2010 17" Powerbook which still works fine. After getting a call back and going through 20 minutes of time, I was told that since my laptop is a "classic" model it is not supported by Apple so they cannot replace the recalled power adapter for me. An Apple Store might replace it they said (see above, but by my brother of course). I said the recall is for the World Travel Adapter Kit, which I bought, not the laptop. Try the store.....
Thinking the laptop I chose was the issue, I tried again later with my other laptop, a 2018 13" MacBook Pro w 4 USB C ports. So after 20 minutes or so I am told they cannot help me since the USB C powerbook was sold when the World Travel Power Adapter kit had already been updated and did not need a recall. Sigh.....
So when I get a chance I will try the store. I could just throw it out, but it still works fine with the power bricks, and if a safety issue then Apple likely wants to get them out of the hands of clients to avoid issues.
Maybe I had more troubles than others...not all customer service experiences turn out the way we expect, or would prefer, them to turn out.
