Meta told a Kenyan court it could only be sued in California. Last week it settled there for $18 billion.
Abrham Meareg has waited four years for a hearing over his father's murder while 29 US states settled with Meta eight days into their trial.
Meta spent four years telling a Kenyan court it could not be sued in Kenya.
Its terms of service, the company argued, meant claims had to be heard in California, where it is headquartered.
Last week, in California, it settled.
On Wednesday Meta agreed to pay up to $18 billion to a coalition of 29 US states that alleged it had designed Facebook and Instagram to addict children.
The trial had opened in Oakland eight days earlier.
Adam Mosseri, who runs Instagram, gave evidence on the Tuesday.
Mark Zuckerberg was due on the stand and never got there.
The money comes with a catch.
About $12.7 billion is guaranteed, paid to the states in instalments over 10 years.
The remaining $5.3 billion is payable only if YouTube and TikTok bring in their own daily time limits and age checks — a penalty that partly depends on what Meta's competitors decide to do.
Meta admitted no wrongdoing.
Its share price rose.
American teenagers get a two-hour default daily limit across Facebook and Instagram, blocks on overnight use, and feeds that are no longer fully personalised.
Australian teenagers got something stronger a year ago.
The under-16 ban took effect in December and Meta says it has since cut off more than 750,000 Australian accounts.
In July the regulator eSafety found more than eight in 10 under-16s were still using the platforms anyway.
None of it touches the algorithm.
Abrham Meareg's father taught chemistry at Bahir Dar University in northern Ethiopia.
In October 2021 two Facebook posts named Professor Meareg Amare Abrha, published his home address and falsely claimed he was funding a Tigrayan rebel group.
His son reported them.
Nothing came down.
On November 3 men in special forces uniforms shot the professor outside his house, in the shoulder and the leg, and kept his family away for seven hours while he died in the street.
Facebook answered the reports eight days after the murder.
Mr Meareg filed in Nairobi in December 2022 alongside former Amnesty researcher Fisseha Tekle and the Katiba Institute, seeking a $2.4 billion restitution fund and changes to the algorithm that carried the posts.
Meta fought the jurisdiction.
In April last year the High Court ruled it could hear the case.
Meta appealed.
"It's a matter of numbers to them, a matter of statistics," Mr Meareg told the Guardian.
"It has been proven multiple times that our lives do not matter to them."
Nearly five years after the murder, Meta has paid — in the one jurisdiction it said counted.
