It was meant as a general notice regarding high end Sigma lenses. Sigma decided not to use drop-in filters on any of their lenses, including way more expensive ones, like the 300-800 or the 120-300 OS. And other brands already used drop-in filters on less expensive lenses (take the old Nikon AF 300/4 as an example)
No need to tell Canon how it has to be done, you should check their sites again. The 200-400 L IS uses the same drop-in filters as the other big L guns. The geared CPL is called "PL-C WII" and is also compatible with the 300/2.8 L IS II, the 400/2.8 L IS II and the new 400/4 DO IS II. Maybe you should occasionally tend to believe people who have actually used the gear they're talking about
And even if a Sigma with a 105mm CPL is cheaper: it's still a lot more hazzle to handle it in the field (which is the polite way of saying: such a large CPL under such a large hood is nothing but a PITA).
