There is one recent printer where that comment may apply - the 3880 - which seems fairly trouble-free with OEM, but it's also true that plenty of people are using it successfully with non-OEM as well.
There is one part that I do agree with, and that is that the older the (desktop) printer, the harder it is to get it to work with refillable cartridges. But that's not an ink-specific comment, it would apply even if you put OEM ink in the carts.
This thread is a little off-topic for the DB&W group.
