The major flaw in Facebook’s planned cryptocurrency, Libra, is that it’s a closed system — akin to a “walled garden.”

That’s the argument made by Marcus Treacher, Ripple’s senior vice president of customer success, in a CNBC interview published on Sept. 27.

“Walled garden” strategies and the antitrust pushback

The “walled garden” metaphor has notably been used in the past to refer to commercial strategies pursued by tech giants such as Apple, who endeavor to retain complete control over the software, apps and accessories related to their proprietary devices.

This very strategy has come under fire during recent attempts to take down these ostensibly monopolistic practices by anti-trust campaigners and lawmakers. The implications for the likes of Amazon, Apple and Facebook — even ahead of its Libra project — are expected to come into sharper view with the conclusion of a major United States antitrust probe now underway.

In leveling his critique against Libra, Treacher claimed that the Ripple network, by contrast, “has no parameter. It connects with all of the players that want to use the technology.”

He nonetheless weighed that it was still a “really good thing” that a Silicon Valley behemoth like Facebook had envisioned for itself a role in the digital asset space.

Libra not intended to replace currencies, says association head

As Treacher acknowledged, global regulators are, arguably, yet more concerned about the potential threat to national fiat currencies that Libra represents — an anxiety that the Libra Association’s managing director, Bertrand Perez, today attempted to quell.

The conference reportedly included speakers from the Swiss National Bank and International Monetary Fund, among others.

David Marcus, the head of Calibra at Facebook, has likewise recently argued against any prospective threat to sovereign monetary policy from Libra, noting that:
