> So many open source projects have risen out of real and concrete needs and successfully made their way into our every day lives.

When it comes to consumer hardware or software targeted at end users? I think such cases are pretty rare and far in between. Firefox had a brief stint of being popular in the late 2000s, Valve is doing some cool stuff with SteamOS/Proton but I can't think of much else of the the top of my head.

Otherwise it's usually companies like Google or Apple which use OSS as a base layer for their closed down and proprietary platforms.

PostmarketOS is cool but its a product niche targeted a very tiny subset of consumers (just like Linux on desktop for that matter).
