Why hate extension methods? Do you really want to write Enumerable.ToList(Enumerable.Select(Enumerable.Where(someList, e => e.someBool), e => new {a = e.x, b = e.y)) and so on?

That would suck, on the other hand, the extension methods make people create huge chains continuations of which comes from who knows where.

Best solution would have been a pipe operator if you ask me.
