> don't think FLOSS has had the kind of effect that many activists were going for

The entire internet, end to end, runs on FLOSS.

That's great, but it's not what FLOSS activists hoped and fight for.

It's still almost impossible to have a digital life that doesn't involve significant use of proprietary software, and the vast majority of users do their computing almost exclusively through proprietary software. The fact that this proprietary software is a bit of glue on top of a bunch of FLOSS libraries possibly running on a FLOSS kernel that uses FLOSS libraries to talk to a FLOSS router doesn't really buy much actual freedom for the end users. They're still locked in to the proprietary software vendors just as much as they were in the 90s (perhaps paying with their private data instead of actual money).

If you ignore the proprietary routers, the proprietary search engines, the proprietary browsers that people use out-of-the-box (Edge, Safari and even Chrome), and the fact that Linux is a clone of a proprietary OS.
