This is a good point. If and as they proceed, they'd better run more than the usual level of due diligence to insure they don't become a vector for something nasty. Google properties are some of the few I let through without a lot of filtering (Gmail in particular). If it looks like they are becoming a vector, this will lessen their utility for me and I will tighten the hatches on them. (Of course, I suppose this factor won't apply for 99% of their users. We may be the outliers having no statistical significance. At least, until something big enough and bad enough slips through.) I have mixed feelings about blocking advertising that provides supporting revenue, but two factors override: Motion (and occasionally, sound), that completely and thoroughly distracts me from the page content and which, over prolonged exposure, leaves me "frazzled" and ineffective; and malware. (Also, when graphics are overwhelmingly "bright" compared to the content, I need to dial them down.) Nothing that hasn't been said a thousand times before, I suppose.
