1. Ads look more like results.
2. Google results got more useless spam.
While 1 is kinda icky it's not that big of a deal, especially since I use an adblocker... and for 2 why does the author think this is the fault of google? Does shittier results increase in more people using google? I feel like it's the opposite, this doesn't seem right to me. Can it not just be that spammers and SEO freaks got more sophisticated and the problem got more challenging?
