It's funny that in one post you states that we should accept ads because "you can never, even hope to change", and then you states that when some other type of ads becomes commonplace "it's time to start bitching". Why should we accept one type of ads and not accept the others, then? After all, "how else are companies, etc supposed to let people know about their products"?
Ads that lengthen loads times is something to bitch about. Ads that appear during load screens will become a normal occurrence soon, it won't be anything to bitch about, but if they increase load times, it sure as shit will be.
