The comment you replied to answered your question. The transaction goes through, absolutely no additional regulation or control comes into play at the transaction level.
NOTE: I am not supporting this position, or opposing it. I’m just stating what the gp post said.
It really didn't, instead it weaseled out by putting up a strawman that pretends to put a loophole in a straight-forward and very clear way.
In fact, it's blatantly clear by itself the fact that no one proposed a single idea or suggestion about how to enforce that mysterious 10%. No explanation was given on the impact on customers, and how the sellers would be forced to not go beyond that 10%. Why is that? Is the idea undefendable?
