You assume Facebook - or indeed the whole tech industry - makes products designed to fulfill a buyer's need.

They don't: they make surveillance products that also happen to have a function that you want enough to buy their surveillance devices.

GM sells surveillance vehicles because people need to go places.
Google makes surveillance software because people need a cellphone and a search engine.
Facebook makes surveillance glasses for perverts who need to record people covertly.

They all have a target market to sell surveillance shit. Facebook's happen to be consistently the creepiest.

You dont. Meta does. Thats reason enough for me to give it a pass.

Even Reality G2. That's what I'm getting. No camera. Just a hud.

When I was riding my e scooter the other day I was thinking how nice it would be if the dash on it could display inside my helmet so I do not have to keep looking down at the dash.

If they don't add in the data collection, their products will cost more than the ones who add it. Same thing happened with TVs.
