It could be a psyop, but it's far from absurd. Tensions between Yevgeny Prigozhin and Putin have been high. Most notable were the public threats from Wagner to pull out of Bakhmut due to lack of supplies. If anyone has the potential to seize power away from Putin, it's Prigozhin.

Prigozhin has an army, one which is vital to Putin's war effort. Do you really think Prigozhin wouldn't turn on Putin given the opportunity?
