He's done nothing apart from;
Meet Sam Allardyce before appointment
Meet Carlo Ancelotti (and discuss transfer targets)
Meet and appoint Rafael Benitez
Sponsor the training ground
Sponsor the Women's team
Provide funds for an option to sponsor the ground
Have his nephew running the women's team
Have his nephew being pictured next to Benitez on the day of his appointment
Provide Moshiri with the funds to purchase Everton
Not shut down reports from Russia and other areas that he's the owner of the club
There's plenty more of course, but it doesn't equate to "not done anything". There is overwhelming evidence there. You might not believe it, which is your right, but lets not make out there's nothing to suggest he has involvement.
