Disagreement Between Djokovic and Pospisil at the Helm of the PTPA?

Exactly one month ago, the PTPA (Professional Tennis Players Association) filed a lawsuit against global tennis governing bodies, namely the ITF, ATP, WTA, and ITIA. The complaint had 22 signatories but also one notable absence: Novak Djokovic, co-founder of the PTPA.
The Serb had indeed stated in Miami that he "did not agree" with certain aspects of the legal action taken by his own association. This reaction somewhat puzzled Vasek Pospisil, with whom Djokovic has led the PTPA since its creation in 2019:
"I was surprised… I don’t know why he said that. It wasn’t in line with our previous conversations," the Canadian said.
Pospisil also commented on the case of Carlos Alcaraz, who had expressed surprise that his remarks were cited in the PTPA’s complaint without prior consultation:
"I didn’t want to distract him. I sent him a message, and he responded enthusiastically. He told me he’d like to learn more."
