This method seems intrusive to me and like an "Ah ha! I stopped your ad blocker from working! TAKE THAT!"
As far as I'm concerned, putting ads on web pages has always been an intrusive an deceitful business model to begin with. I sincerely hope that there will come a day when advertising via ambushing consumers is no longer considered acceptable.
If you know you will be ambushed and robbed on your way through the forest, would you also say "well, that cannot be helped, people know that when they enter the forest" (excuse me for the rather harsh analogy, it's the best I could spontaneously come up with).
It's a few hundred pixel banner that's trying to convince you to buy something. Not a requirement that you sacrifice your firstborn.
Yes, and that's undesirable to a lot of people. It's distracting and, depending on the intrusiveness of the ad(s), annoying to outright rude. It's gotten to the point that it's hard for me to use the internet when I'm on a computer without a decent ad-blocker. Imagine trying to read a book while a bunch of persons are screaming inane stuff at you; that's what it feels like.
Actually, I long for the day when display goggles and computer vision have advanced far enough for a "real-life ad-blocker". The world would be a much better place.
I didn't intend to liken displaying ads to heinous acts of infanticide or anything of the sort.
Frankly, I prefer ads since I can ignore them, where as if I ignore paying I don't get the service.
