This isn't about banning any sponsor its related parties Take Etihad as an example, owned by the Abu Dhabi government, Sheikh Mansour has no monetary interest nor management influence and this is enough to say in accounting rules and accepted by CAS that they aren't a related party. My guess is that this proposal is to change the PL's own rules that would make them a related party, because his relatives do have responsibility. It could also mean that if one of the companies that Silver Lake have a major investment is could also be deemed a related party thus ruling them out as sponsors
