I'd rather just pay money for a finished game, and not have to be a continued cash generator for a terrible company.
I'd certainly not be willing to sit through longer loading/wait times (and we all know AAA publishers would artificially inflate times) to watch trash adverts.
They keep peddling the excuse that games are too expensive now, but who's buying that? Maybe stop urinating so much of the budget on terrible marketing...
The real problem the top publishers have is that they are scumbags, with no interest in the health of the sector they're in. They only care how much $$$ they can bleed out of it.
