Haven't you noticed that the word "recycle" is used here in the exactly opposite way than it should be? https://www.merriam-webster.com/dictionary/recycle

This is purposeful marketing misinformation. The goal here is to incentivize a naive customer, apparently including you, to make their devices non-reusable and to buy new devices.

This isn't even a new technique. Unfortunately, it's widespread. Yet another example of greenwashing: https://en.wikipedia.org/wiki/Greenwashing
