Let's see. One test I'd apply is that no big club has ever? managed to offload that many expensive contracts (~40M / yr) in a single window.
In my book if they succeed, it means that they were forced to do so and had to adopt some unethical means. Spanish clubs are motivated to spin this, so I'm sure they'll get their journos to dig.
The thing that I don't udnerstand here is that you have a list of players that aren't needed and have been barely used by PSG but somehow insist on linking it to something that happened earlier this month.
Just to illustrate my point in the league last season, Kurzawa played around 0 minutes for PSG last season. Paredes played 800 minutes, Abdou Diallo 800 minutes, Icardi 1k minutes, Herrera 1k minutes and Draxler 500 minutes. All of these players are at best third options and some are 4-5 options with both Tuchel and Pochettino choosing to use players out of position before using them. It has nothing to do with Mbappé or FFP or PSG being mean, they are just their deadwood.
Also the list is a speculation from Le Parisien after Al Khelaifi said that certain players are for free to go but that if they want to stay, they will have to fight for their place and that coasting won't be accepted.
