If the pitch here was that vendors were lying about cloud/connectivity requirements, and we wanted legislation to prevent them from obscuring the truth, I’d be 100% down. Thankfully, we already have those laws.
The IKEA bookshelf doesn't violate your privacy nor have an always on connection to a much more powerful entity always looking to make another buck.
The IKEA bookshelf isn't an avenue for your attention and your time - whereas things like gambling (considered addictive and regulated by almost everyone) are - and we regulate them heavily.
Why would Facebook with its billions be exempt from regulation? It's not something we "want" - its to make their product basically useful without the IKEA subscription service to make sure your shelf doesn't fall apart every month.
Along the same lines, the law should say Facebook can't sell hardware that forces you to give up all your privacy to protect the individual.
This is not "I want Facebook to design a headset with blue stripes", this is "I don't want to be forced to give up my private data to use a product that would work just fine without".
I think the difference between the two should be obvious.
