I agree totally agree to your update: it depends on how you "grew up".
For me it was learning C by reading the "bible" (K&R) as well as other books - and I really disliked the K&R-style (no own line for the opening brackets).
And it were the tools I used for coding then (vi (without syntax-highlightning ...)) - I often got errors due to missing brackets ... and found it much easier to find them if the opening brackets are on a line on their own...

Fortunately, my current company has not defined a style-guide on this topic - my previous had, which led to endless discussion (which style is the better one, how to enforce it ...) without making the code any better.
