But apple (and Android) allowing search providers to bid/buy that default spot is a barrier to entry for new search providers and only makes the dominant search provider stronger. How could a new Google emerge today when people lazily accept the default? When Google started there was not built in browser default - users had to manually type in altavista.com or google.com.
A big company like Coca Cola being able to buy huge advertising campaigns is a barrier to entry for new Cola makers. I suppose there are cases where buying or selling placement might be unethical, but I don't see it here. For example for a long time Google funded Firefox by buying a place as the search default. Was that unethical by Mozilla?
