WildBillbakerhil: It ain't helped me.
As said several times already you can block them for nothing. The group I never addressed are the people like you. Suspect you are a non gamer / pre computer age person, and they won't miss a trick to lift and extra $5 from you. I guess many of us are all old enough to recognise a used car trick, and they are helping the one born every minute every day same as those places:)
Can't help but think on the high street that claim would at least be tested, and they would held to account if not true. Definition of "significantly" probably means no clue to zero difference is my starting guess, LOL.
Anyway as said in the thread just use a a free ad block, and it will delete all ads. If you don't know how just ask:)
EDIT:
Just out of interest does the mobile version have an issue with too many ads? Of it does is there an ad block for that ?
