The attempt by the DFB to sell future broadcast revenue to an investor was blocked by fan pressure after massive protests (as you probably know). And that doesn’t look like it’s coming back (which is a good thing).The issue with that, is this is a matter each league. But in Europe, the leagues are competing against each other for resources and talent.
The argument in Germany, for example, is the Bundesliga wants to bring is fresh, private Capital to help it rebuild its broadcast rights to complete with the EPL. The spending power of the EPL, means that talent from Germany flows to England. And purely from a business point if view, that's problematic.
But football isn't just a business, it's a culture too. In Germany, where the fans have a real say, while they might want better product, their opposition isnt the shift of the focus to overseas TV, its the concession to private capital that would warp/distort their rights in the game.
And then you multiply this by the top 5 leagues in Europe. Then the next 15. And so on. And barely any league in Europe would want the constraints and consequences of wage caps.
You only have see the panic caused by the Chinese and Saudi leagues to see why
Some clubs - including my local side - have spun their mens‘ first teams off into a separate legal entity, and invited commercial investment into that company, whilst the parent company (owned by the fans, as in „50+1“), still has a majority ownership. The VfB has just trousered €41m from Porsche, for an 11% holding in the VfB Stuttgart A.G., the limited company that runs the first team; given a similar-sized previous holding and investment from Mercedes-Benz in 2017, and a somewhat minor, more recent one from local sportswear company JAKO, the „members“, as in the VfB Stuttgart e.V., (of which I am a member) still controls around 78% of the A.G. company.
This has not been entirely smooth; there have been rumblings and discontent about the board of the A.G., in that the Chairman of the A.G. Board, Claus Vogt, was recently-voted out by the other board members - this is important (and controversial) because by agreement from 2017, when the A.G. was set up, it was accepted that the board of the e.V., which is the parent association owned by and run by club members (who of course, also elect its board), was to be given the right to nominate the chair of the A.G. board, and that chair would be a member of the e.V. This has not gone down well at all with the members, but then, there’s always some wrangling going off at the VfB.
The parent association (the e.V. company) is still owned by its members of course, and acts as a parent to not only the A.G., but also the other multi-sports branches of the VfB (including, nowadays, e-sports!)
