Although a lot of this thread has focused on the issues of UA spoofing, if you're using NoScript, I'm inclined to believe that's the problem. I
I also make extensive use of NoScript, and in my default settings, I see the same kind of blurring at The Globe. A check of NoScript shows that when I arrive at the Globe's site, scripts presented by bostonglobe.com, googletagmanager, chartbeat.com, blueconic.com, amazon-adsystem and 3 different hosts at cloudfront are all there.
With a little trial-and-error, I find that if I enable bostonglobe.com, then the photos resolve correctly. If that scripting host is enabled, then I see no problems with photos with the default UA, and no spoofing is needed. However, the trade-off is that the scripting host that runs The Globe's paywall, and it takes clicking only an article or two before you get nagged for a subscriber login.
I've found the same effect at bleacherreport.com, where photos get blurred unless I enable the scripting on that site.
When it comes to enabling or disabling scripting hosts, chartbeat, blueconic and amazon-adsystem are all advertising related. As a general thing, I've found that at many sites (but not all), it's desirable to enable cloudfront's hosts, as they often deliver content I want to see, although I don't enable them (and often per-visit) unless doing so seems to be necessary to see content I want.
Googletagmanager is an odd beast. I'm generally suspicious of enabling anything Google, but it's not uncommon at many sites that if I click on a link and get no response, it takes enabling googletagmanager. The same kind thing tends to apply with other Google hosts (including cached fonts at gcion.com), although which Google hosts need enabling vary from site to site.
By my experience, the only Google scripting host that seems to be exclusively related to advertising and tracking (and where it's always safe to block without disrupting content or navigation) is with Google Analytics.
