Yes, you are correct. Our users are the site owners, and their users are the ones who encounter Apture and similar "apps" in the wild. This is why, as I've said in other replies, the suggestion that we provide an easy opt-in / opt-out mechanism is well taken.
I _want_ to make this something that is elegant and useful, not just from the average internet-goers perspective, but also from the perspective of my peers and colleagues (and luckily, I'm in a good position to do so). I'm glad that some of the readers here have been willing to offer constructive and valuable suggestions about how I can do that :)
What you guys are doing would be the equivalent of Geocities offering a one-click-install animated rainbow GIF background for websites... Just because lots of the Geocities customers would have chosen to install such a 'product' doesn't make it a good idea for the users down the line ;)
Of course it's not your place to determine how your customers interact with their users, which is the point most people in this thread seem to be missing. This is good marketing for CloudFlare, plain and simple; if the users of your customer's site don't like it they can complain and/or stop using the site.
