Although this list is a scant 4 items, none of its items are older than December. I happen to believe all sorts of edits are happening on Wikipedia, but they are just going undetected. 
The article on Zarqawi led me to believe this, as references to a years-old CIA report claiming he was dead/missing a leg kept disappearing from the article. I wasn't paying close enough attention then to find out who.
This ""crusade"" is good for Wikipedia because it will defuse future endeavors by propagandists by making their actions public and documented. Apologizing for Jack or anyone else by saying he's ""just your average biased editor"" is _________. 
Your ""field of interest"" expression of misunderstanding/classic ""extreme worst case"" argument is addressed repeatedly in the article. See such phrases as ""surrepticious [editing]"", ""investment"", ""direct involvement"" or ""financial or political involvement"", etc. Sure, by some wacky logic you can connect everyone in these ways.
