Well let me make it a bit more clear. Pretty much nobody who donates redeems credits for the base rate of $1,000,000 (the exception being during war-time embargoes). They all either use the credits directly for the aesthetic items (VIP/flags/pips/ads) or they sell them on the market. Very few people are going to be making ads if it's just going to result in dozens if not hundreds of people embargoing them (along with all the annoying notifications). Credit demand will drop on the market (I alone probably buy 1/5 to 1/4 of all market credits every month). Donations for credits will follow with the decline in credit prices/demand. Sheepy will make less money. The existing VIP feature will be mostly pointless.
