I can compare them, and I did. The comparison was largely 'color', but I suppose if you are determined to pick an argument you will find cause for one anywhere. The water your motorcycle is exposed to may be somewhat acidic, and lacking in anti-corrosives, but it isn't steeped in it all day, or at temperatures above ambient, and yet, nevertheless, corrosion occurs.
Moreover, I fail to see a point here? Do you mean that anodized waterblocks don't corrode? We have seen plenty of pictures that show that they do, so it's pretty hard to argue that point without being plain contrary. As for the impact of that corrosion on the entire system, and whether it resulted in destroyed equipment, on that point there is plenty of room for debate.
The final 'icing' on this cake is that I was making a point about plating being confused with anodization (yet again) by people who seem to be lazy readers (if I give them the benefit of the doubt). If I wasn't giving them the benefit of the doubt, I'd say they were doing it on purpose, just to get attention.
And just for those lazy readers, I'll point out (again) that imperfections in the plating would not necessarily completely negate its protective value, because it's based on a zincate layer.
That said, if the block did have an imperfection, we've already established that anyone other than a complete muppet would discover the problem long before it did significant damage to other components in their system and they could get a new (presumably un-flawed) block from Swiftech under their 5-year guarantee.
