I appreciate your story but open source projects don't inherently deserve to survive. Businesses don't inherently deserve to survive.
More importantly, the fact that Facebook can and has saved lives doesn't make it necessary for survival either. I'm sure a Taylor Swift song has brought someone back from the brink of suicide and indirectly saved lives by some definition, but it would be absurd to consider Taylor Swift songs to be a public utility necessary for survival.
But, the project I worked on is definitely not something to be compared to a Taylor Swift song, and I understand that this comes from a position of unfamiliarity. That's fine, but I'm happy to elucidate, offline, if you wish.
It's the kind of thing that is best left relatively "uncredited," and is important only to a certain demographic; but within that demographic, it is very, very important.
I ran an open-source initiative for ten years, barely making headway.
Then I set up a Facebook group for it.
Within a few months, its reach had exploded worldwide, it became the de facto world standard, and a huge new team had taken it over.
It was not all Facebook, but the Facebook presence was a big part of it. It’s the most active hub for that effort by far.
Also, due to the nature of that particular effort, I guarantee that there are people (probably many) that are alive today, because of Facebook.
It’s entirely possible to hop in a sailboat, and get to Hawai’i, but most people would prefer flying there.
It can be said that Hawai’i requires air travel to “survive” (but I suspect that there are a number of native Hawai’ian folks that feel as if this ease of access has been anything but a blessing).
