The Connecticut-based online travel company, which generated $9.2 billion in revenue in 2018 and has the world’s largest business selling accommodations, wanted to avoid the controversy that’s developing around Libra, a source said.

That controversy includes pushback from regulators in the U.S. and France. Regulators have argued that Libra, a project initiated by Facebook that would be run through the Libra Association, could contribute to undermining the global economic system.

Booking Holdings hasn’t ruled out getting involved anew with the Libra Association in the future, the source added.
