It seems Mark Zuckerberg isn't the biggest fan of his fellow tech titan, Jeff Bezos.

The Facebook CEO liked a meme on Instagram mocking Bezos following Bezos' jaunt to the edge of space on Tuesday. The image, posted by popular meme account Tank Sinatra, showed a still from the 2019 film "Joker" and read: "Amazon workers listening to Jeff Bezos thank them for sending him to space."

Zuckerberg's like was first spotted by The New York Daily News.

Bezos made headlines following his brief spaceflight for thanking Amazon employees and customers, saying, "you guys paid for all of this." His comments rubbed some Amazon workers the wrong way, who told Insider that the Amazon founder is "making money off treating workers like slaves."

Bezos' spaceflight was heavily criticized across the internet, including by Rep. Alexandria Ocasio-Cortez and Sen. Elizabeth Warren, who said the trip was extravagant in light of Amazon warehouse working conditions and a report from Pro Publica last month that Bezos didn't pay federal income taxes for at least two years.

Zuckerberg didn't make any public comments about Bezos' spaceflight, and the two moguls don't seem to have any pre-existing animosity. While they were both brought before Congress last summer for a wide-ranging antitrust hearing, their respective business ventures rarely intersect.

But both execs have been caught up in rivalries in the past: Zuckerberg has publicly feuded with Tesla and SpaceX CEO Elon Musk and Apple CEO Tim Cook, and seems to have long-standing beef with Twitter and Square CEO Jack Dorsey, Snap CEO Evan Spiegel, and Instagram founder Kevin Systrom.

For his part, Bezos has been locked in a public rivalry with Musk for over a decade over their respective space ambitions.
