I'm not really sure why your comment was down voted, it seems like a reasonable question to me. Just because something is open source doesn't automatically make it better (or worse) than a proprietary (in the sense of closed source) solution [1]. But if it isn't adopted by all of the __other__ browsers, then you're back to the same situation of having a fragmented browser experience, reminiscent of the "best viewed in Browser X" issues, some of which continue to plague developers today. I think it's legitimate, at least for some concerns, to compare NaCL to ActiveX, and be mindful of these concerns so that NaCL does not repeat some of the mistakes of ActiveX.
