That probably tells you more about the haters than the brace style. That was my career path, and while I've gotten used to reading Allman braces, I've heavily relied on tooling (especially Visual Studio) to auto-format my K&R (or 1TBS) braces for whatever project I'm in. Same thing with tabs/spaces.

There are lots of sane ways to read code, but consistency is key. It's hard to change muscle memory in how I type, though, so I think auto format is the way to go.
