It's not just the PSG because Messi himself also wanted to have freedom away from them because of the toxicity they've showed recently when he visited Saudi Arabia, hence why he was not looking forward anymore to play with the PSG. Well, the truth is, it is the PSG who are turning the tables to look like they are the ones who freed Messi when the in-fact it was Messi who gave up on them.
What is the toxicity of PSG if Messi violated the terms of the contract with his visit to Saudi Arabia, for which, by the way, he later apologized?
If we think globally, we can say this: after a disastrous first season, PSG gave Messi another chance, but it was not used and the parties decided to disperse. If Messi was worth something, he would easily go to City, Bayern, Liverpool, etc., but for some reason he retired to MLS.
