Agreed. Per http://en.wikipedia.org/wiki/Wikipedia:BOLD I replaced the offending article with something aiming for a middle ground and shamelessly stealing some of your references (thanks!). See http://en.wikipedia.org/w/index.php?title=Mathematical_object&diff=242209011&oldid=242199687 for the previous version. It might also be worth mentioning coalgebras, and perhaps more importantly dually defined structures such as locales which are understood better in terms of the morphisms from them to a cogenerator rather than those to them from a generator, i.e. dual elements rather than elements. Also toposes as a more general codomain of the forgetful functor than the particular topos Set. Thanks for pointing out this article---Wikipedia is full of problem articles like this and finding them and getting them into shape is an ongoing project. Vaughan
