"Before the fluid, how did the larger screens had no such enlargement?"
 * Before fluid everyone had the same content area and (to my recall) the same font.

"But they didn't just revert it,"
 * They didn't revert it. If they did, the content area would be even smaller for larger screens.

"Of course those who didn't care how it look on larger screens, are innocent angels, as it should only be cared for smaller screens, not for larger ones."
 * Again, if Wikia only cared about smaller screens they would have completely reverted fluid. Fluid made designing layouts difficult, especially those targeted at large screens (if you were concerned about other sizes). On the main wiki I edit on, I actually created a template (used on a quarter of the wiki) solely to make articles look better on larger screens without compromising the view for smaller resolutions.

"Wikia wants everything to look same on across all platform."
 * Clearly everything is not the same. The goal is to have the amount of content roughly the same so formatting is easier. Personally, this is the approach Wikia should have taken instead of Fluid.

Edit:

"In any case, this update also solves the problem of people optimising their layouts only for smaller screens. For instance, images to the left and right of paragraphs will no longer be "bunched up" due to the paragraphs being shorter when viewed wide."

I encountered this issue to some degree for this article not because I was optimizing for smaller screens but because some screen sizes were plainly just too big, stretching paragraphs. The page didn't look too bad for large screens but it actually looks much better now.

"I know of at least one comment where someone has expressed concern about not being able to preview properly at larger screens"
 * I didn't specifically comment on this issue but it's bothering me too as I do spend much time trying to make articles look good for everyone.
