The more I think about it, the less I'm convinced that there's something shady going on as far as why these articles were released.
I don't believe Bayern orchestrated this at all. They've had more issues with Der Spiegel than anyone over the years.
I honestly think this is entirely down to to German football fan pretension. I don't know if you've ever had the privilege of speaking with a Bundesliga fan about their league, but it's not too dissimilar to talking to a Liverpool fan. They're especially keen to talk about how amazing it is for the fans.
In Germany, they only pay pennies for tickets to games. They have safe standing. They have better booze. They average 70,000 a game everywhere. They have tifos. They have the 50+1 rule. They even have Jadon Sancho.
Basically, as far as they're concerned, football literally belongs to the fans. There's no set of people more arrogant about doing things the right way. The levels of grief Hoffenheim got a few years ago due to their heightened investment was immense. The way RB Leipzig are villainized beyond reproach is ubiquitous. I'm aware that a blind eye is turned to Bayern and they're somewhat worshipped by many, in fact I think that served as the authors's motivation.
There's a real, 'How dare they?!' about the whole thing. How dare they buy De Bruyne from Germany? How dare they buy Sané and Gundogan ahead of Bayern? How dare they beat the rules that were set in place to hold them back?
There's so much angst in the article, so much anger. By the end it felt like I was reading something off RAWK. I honestly think if there was some higher power behind it all they would have wanted Der Spiegel to do a better job.
