your framing is wrong at multiple levels.

i) facebook has not contributed an iota to the consumerist utopia you seem to cherish. it is the result of a long period of scientific / technological development. communicating instantly with people around the globe can be done perfectly well with, e.g. Signal. you do not need the apparatus of surveillance capitalism to deliver it.

ii) said consumerist utopia is neither available to large fractions of humanity, nor is it environmentally sustainable for those who currently enjoy it beyond a few more decades

More fundamentally, if we do not develop "social media" that are trully social: actually promote global mutual understanding, support fact based consensus, promote the genuine empowerment of individuals instead of exploiting and aggravating their ignorance etc. many of the real gains and progress (<ref>Hans Rosling</ref>) achieved in the past century will be squandered, never to return

Facebook hasn't contributed one iota? Facebook has contributed an immense amount to the developer community, small businesses and literally everyone else.

Free communication with almost any human on the planet: check. Advertise alongside industry incumbents with any ad budget: check. Oh yeah and React, React Native, GraphQL, pyTorch, and a whole lot more.

"Free communication" in... exchange for personal data. But thats a price that is invisible to fanboys. Exploiting those who either can't understand or who can't afford the tiny cost of communicating with data privacy.

As for small businesses, its walled garden simply cannibalized their earlier websites and made every small trader dependent upon opaque and arbitrary discovery algorithms that can wipe them out without warning.

The open source projects you mention have multiple alternatives, many from genuine community projects that will sustain irrespective of a corporate sponsor.
