This is a non-issue and you are projecting your own fears on others.
I work on very large projects and frankly, some of the code is utter crap. Still, if someone came along and criticized it without offering patches, they'd be the one looking stupid.
I have not been here long, but my current company has absolutely no culture of shaming code. People do some pretty egregious things, and not just in terms of adherence to style, and their work is still lauded if it runs fast.
