Ubisoft DRM Creates Security Vulnerabilities

Greetings, dear readers. Obviously, the first thing that comes to mind when you read “Ubisoft” is “opressive DRM”. (”Poorly written, borderline racist novels” is acceptable too.) But what happens when “oppressive DRM” combines with “poorly written browser plugin”? According to what I read on Ars Technica, for a little while today, Ubisoft’s Uplay DRM scheme would, upon the user browsing to the wrong page, allow a site to run any (possibly malicious) code on the user’s PC. While Ubisoft has since patched this issue, the problem still stands: Why should someone have to install restrictive, ineffective (DRM does little to nothing to stop pirates while making things much harder for legitimate customers) and sometimes ineptly written software to use a program they bought a license to use?
I don’t know why someone would do this – Uplay is exactly why I will not send Ubisoft a dime for anything.
