It's sort of like asking if you can't raise an objection without invoking fallacious logic, how are you going to make interesting contributions to this community?
I don't think it is poor reasoning. I was making an observation about their technology prowess. And where most people were expressing their opinion about whether or not ads are bad which has been discussed at length, I thought I'd make a different point. My argument is that if improving browsing experience is the purpose of their service and removing ads is one of the ways they do it then I hope they pay attention to page bloat. I wanted to point out that they hadn't paid much attention to javascript page bloat in their own web page.
