>>As every VFP'er knows, EOL is to be feared. ;-) Most likely we'll install W10 on one of the test machines and use it solely for testing.

>>As for blocking IP or re-routing addresses: I agree, trivially easy on the PC or router. It might even become a point of difference for free wireless or other providers : "no data slurping while you slurp your Starbucks!" That's not your typical corporate mindset but the opportunity for some legal rebelliousness that does over the Borg will be too difficult to resist in some quarters. ;-)

>As AdBlock in the Plus version has donned a black hat in at least some areas, another front for such entrepreneurs is not really needed...

Defining "unobtrusive" in Ads by having companies pay to be on their white list is questionable enough. There were some articles describing a small network of owners and leading people from the more unwanted area of "affiliate networks" and some accusations that they try to split click revenues from Amazon or similar ads by changing the cookie URLs, which in my book would be black hat behaviour. Did not follow up in depth, but sounded ugly.
