Eventually. It's a long slow arc. But there's definitely a history of it. From its Inception the modern smartphone has been built almost exclusively on top of Linux or BSD. Even if proprietary presentation layers above it don't always make it perfectly clear. Similar can be said for any modern gaming console or hand held. With the exception of Microsoft's products.
Most of the modern internet, your home consumer router and maybe even some of your appliances. Built on open source code. And finally, many are switching to own their PC again. There isn't a lot of hype or fan fair publicly. But open source has been quietly putting in the work and showing up for decades.
Realistically, we're actually just returning to a pre Microsoft state. Granted before the explosion of the personal computer most computers were massive devices an individual couldn't own. And there wasn't a lot of money to be made in selling the software itself. So there was a lot of collaboration and sharing. Even if proprietary layers were built on top. The base was vital. We're finally getting back there.
