My point, to a first approximation, whether you're right or not, is that it doesn't matter.
No one at the heart of FOSS, now, or ever, had anything approaching the resources and influence on the rise of ubiquitous computing and the shape it took as those in computing outside of or peripheral to FOSS.
Gates and Jobs everyone knew, and many still do. But that FSF guy? Or the kernel guy? What? No. Totally in the noise for most computer users, and often no more than a curiosity even to many devs.
They never slew Goliath. It was all they could do not to rack themselves up with the sling every time they took a swing.
The responsibility many of us try to pin on them is a measure of our disappointment and disillusionment much more than in what was ever really within their, or our, reach, whether what they oversold was "ethics" or "quality". It's very inside baseball.
For what influence there was, it was always fractured, from the earliest days of copyleft onward, long before "open source" even.
They rose just high enough in relevance to be consumed by the big fish.
I mean, seriously? IBM was a tentacled horror from the deep when Microsoft was the upstart! Let alone when it ate Redhat that had eaten Cygnus that had commercialized the GNU build tools.
who even knows about Cygnus any more?
it's not like they ever had an open field and just fumbled it. It was always a long shot, and it took some very weird and unreasonable people to achieve even as much as they did.
