Say someone produces a reading chair. Now say the company desires to restrict, shape or dictate which books one is allowed to read while sitting in the chair.
One could argue they should have such rights but historically it is quite unusual.
Similarly, if you pay for the chair and put it in your home it is tempting to think you've purchased it and that you own and control it.
The tos could state that the company may at nay time introduce a monthly fee, render the chair unusable or force you to return it without providing a reason.
They may revoke the unisex version and force the user to choose a sex or limit the license to a single user.
It could introduce tools to measure the weight of the user and use that to determine a violation of the single user agreement.
A popular book vendor might require you own one of their competing reading chairs and disallow reading in other chairs.
The company building the house can also grant it self all kinds of privileges. You must buy compatible appliances. They can put some weird connectors on them with some drm logic. np
The only reason not to have such possibly wonderful eco systems imho is that we already have hundreds of thousands of laws and regulations.
If we are to use and make products it should be as simple as possible. Using your weight to check if you are the registered user is not the point to start fixing it. The law should simply state that chair and subscription are separate products.
