Presumably this is what you're referencing:
https://www.businessinsider.com/facebook-lawsuit-zuckerberg-cede-control-stake-2020-1 

"Four tech firms — two of which are now defunct — are suing Facebook on antitrust grounds and demanding that Mark Zuckerberg give up control of the company."

"The four companies are Circl, an online marketplace and social network; Beehive Biometric, an identity-verification firm; Reveal Chat, a chat app; and Lenddo, a financial-services provider."

I'm having trouble connecting the dots to Zuck himself, as these (in some cases erstwhile) CEOs don't actually seem to know him. I admit your premise is plausible, but not sure if we can get from A to B without more info on each of these VC pits, their backers & C-suite. This would be helpful to that end, if anyone has access: https://www.law360.com/articles/1235382

Interestingly, Beehive Biometric was partly run by Mary Haskett who is now CEO of a different biometric startup titled Blink Identity. From their website: "With decades of experience developing identity systems for enterprises in high-risk environments, Blink Identity’s biometric matching system utilizes military-grade technology to reliably identify people at full walking speed in any lighting condition." Their solution (facial recognition) reconfigures military tech for stadiums, stateside. Would be good business if they can convince your average sports fan to link their season ticket purchase to a biometric profile. From what I can find, Beehive was doing something similar.

So what the fuck does that have to do with facebook?

Another weird bit is that Lenddo is an Omidyar property, one which some of you may remember as the US's private-sector counterpart to China's "Social Credit Score," where a credit score for an individual is determined by many factors, including social media presence. I use "private-sector" here loosely, it's intimately linked with USAID (and thus CIA) and is a way of scooping up another billion people into the global financial markets. In NGO language: Lenddo and EFL Team Up to Lead Financial Inclusion Revolution. That's a press release announcing their merger with another USAID-backed "global company that provides psychometric assessments for largely unbanked people," titled EFL. EFL was born at Harvard before incorporating in the Phillipines (both founders American) and is headquartered in Singapore - any red flags yet? But this is all a big digression.

Again, is Facebook even remotely involved with these markets? Has Lenddo been muscled out of some contract that we just don't know about? From what I remember internet.org crashed and burned, and private banking wasn't even the point! I suppose private banking isn't really the point of LenddoEFL either, as once they are a financial institution with up to 1b customers they'll be in the god-tier of financial institutions, repackaging their debts and assets into all sorts of new tradable instruments, and of course, they'll be much too big to fail. Besides, think of the poor peasants you'll be hurting by not bailing out their loansharks!

I don't care about the other two frankly, probably just trying to recoup some losses.

I probably got some of the details here wrong but you get the gist: two of these companies seem to be complaining that facebook has monopolized social and biometric data collection. Not only does this seem manifestly untrue it seems difficult to provide even a lick of evidence for the latter. Something's fishy but I'm not totally buying the Zuck fortune exfiltration story. I guess I understand why LenddoEFL wants in to facebook's walled garden, but their status as basically a front for USAID / CIA "development" ops in areas beyond (or just within) facebook's grasp makes me wonder why they want access to facebook's market-share. Are there that many unbanked facebook users?

more evidence please
