Thank you! A minor quibble would be that the wiki name 
HTTPS-and-Advertising seems to scope the discussion to a particular item in 
a possible threat matrix rather than to the deeper set of issues which seem 
to be along the lines of:

* What sorts of content manipulation by proxies should be appropriate,  and 

* What is the correct role for possible more widespread deployment of TLS 
(or other encryption/signature technology) in limiting the ability of 
proxies to inappropriately modify content?

* To what extent would that more widespread deployment of TLS also hamper 
more legitimate modification of content by proxies (if any such 
modification is legitimate)?

* To what degree will more widespread deployment of TLS cause those who run 
proxies to inappropriately spoof certificates in an effort to retain their 
ability to modify content?

I may not have the above exactly right, but scoping only to advertising 
seems a bit off the mark. I do realize that my retitling of the e-mail 
thread did use the word "advertisements", so possibly the problem traces to me.

Thank you again for acting on my concerns!

I would like to believe that such content alteration is non-conforming, but HTTP does allow for some transformations, and provides a header to prohibit such transformations being done [1]. In any case, I will leave it to others who are more expert in HTTP to decide whether insertion of advertisements is or is not conforming to the pertinent specifications.
