You mean like smartphones, proprietary operating systems, streaming devices, many (most?) IOT devices, digital books/music/movies and a host of other things?
Sorry, until there's some law/regulation (e.g., broadly confirming the First Sale doctrine[0] and/or similar stuff) that ship has sailed, my friend.
In fact I would say barring some very strong laws that make de facto locked down devices outright illegal, there will always be more proprietary devices than libre ones. One of the chief goals of locking down computers is decommodification, meaning taking what could be a general purpose device and restricting it to one specific purpose. Even caring heavily about software freedom - I've got two librebooted desktops, two me_cleaned laptops, one microG phone, but still countless purpose-tailored devices that perform some proprietary function. If those proprietary functions (eg Google Voice SIP integration) could be straightforwardly done with libre software, then I could just consolidate those functions into the libre infrastructure.
The eco-agenda is the provided pretext that will mean we willingly accept what is offered, in the name of saving the planet.
