"Web tripwires" reveal 1.3% of web pages altered in transit

Will integrity issues be heating back up?

... probably not. It looks to me, based on the project page, that the vast majority of modifications come from local proxies the user is running, and the remainder is just on-the-fly image compression, which I am broadly not opposed to, as the human perception integrity is mostly maintained. (Not in favor of, mind you, but not opposed.)
