Victim blaming? Who is a victim? You? Because you expect the world to spoon-feed you everything you need to know? Return the fuckin thing and get something else. Maybe you could write the better business bureau a letter about how your speaker isn't perfect for you.
I bought an advertised small portable Bluetooth speaker. It didn't tell otherwise on the packaging. Nor at the store.
You might blame the store for not informing me correctly. But blaming me for doing the wrong thing is quite an interesting move.
Btw. not advertising the necessity of transmitting all your data from usage is probably not covered by the GDPR.
