I guess you could call that exponential instead of multiplicative, but I think the point stands either way. Not sure why you're blathering on about mechanics that - don't - require the entire raid to do something correctly, as that isn't what I was talking about in the paragraph that you (partially) quoted and were apparently responding to.
Regarding mechanics that don't require the raid to do something correctly - so like survivable raid damage or whatever - I think those fall in to the category of ways for Blizzard to counter the above effect. Potentially. Obviously whether a given effect is harder on 10s or 25s is specific to that particular effect. And it's hard to discuss whether these effects are harder on 10 or 25 objectively, highlighted by the fact that you seem to think having 12 noise cancellation spots for 10 people on Zor'lok is somehow more challenging than having 28 spots for 25 (if after re-examination you still need this explained to you, let me know!).
Your reference to unseen strike, again, is based on poor math and poor overall comprehension of the subject. Yes, obviously one person missing it in 10 is more problematic than one person missing it on 25. But that's comparing apples to oranges. Given equal groups, one person missing it on 10s is as likely as 2-3 people missing it on 25s.
And, of course, you tellingly totally ignored the part of my post about enrages, DPS checks, and HPS checks being much tighter on 25s.
