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.
As someone with prosopagnosia (face blindness) these types of glasses would be an incredible assistive technology for myself and others like me, but even I’m aware of the significant privacy concerns and don’t feel the benefit outweighs the societal risks.
