Quite a stretch.

The open source stuff is nice and all, but I wouldn't say React, GraphQL, Cassandra, or any of the other stuff is "beneficial to humanity" lol wtf

> facebook marketplace

Craigslist exists, plus other startups were aiming to do that and one would have found its footing if not for Facebook marketplace. Either way, this doesn't make up for any of the negatives people ascribe to Facebook.

> messenger connecting people

This is a fucking joke, as there were and are numerous other instant messaging apps.

> low cost distribution for small business

Yeah, small businesses can have Facebook pages, but this isn't that beneficial. We are talking "extremely beneficial" here, not "some features are useful to some people".

> crises and humanitarian tooling

Yeah I can see it being useful for governments to communicate, but unfortunately outweighed by the misinformation

> abuse/spam/threat detection at scale, etc

Cool that they try to solve problems their platform is susceptible to? They are doing this for themselves and it's proprietary software, isn't it?

IDK what kind of bubble you exist in where people genuinely believe any of the above would constitute "extremely beneficial". Large quantities of people, including those holding down jobs, in the richest country in the world are barely able to put food on the table, people are getting kidnapped by masked Federal agents who are entering homes without warrants, and there are multiple ongoing wars in the world, but, yeah, Facebook, "extremely beneficial", solving the hard problems xd
