>they would be able to watch you walk around the store on CCTV
That seems like an unfitting comparison.
The problem doesn't arise in the store, but when using the product at home.
The equivalent of store cctv in this comparison would rather be a server log on the Mozilla website (where people get the product). It's fine to do telemetrics there without me consenting (as long as it's only used by first party) if you ask me.
But after I leave their premises it's none of their business how I use the product.
Sounds like you want it to be ok that your newly bought pack of condoms sends out a message to the factory once you open one.
