TL;DR: you now need to pay a $20/month “meta premium” subscription to use a 100% offline feature that runs on your own malware-ridden smartglasses.
If you don’t subscribe, you can use the feature that is already included in the hardware that you already paid for 3 hours each month
The now-paywalled feature boosts the voice of the speaker in front of you, something that even low-end ANC earphones are doing now. 5 minutes of free usage per day is basically nothing.
I’d say this is more like the middle of the end, with the beginning of the end being the Meta logo on them.
