Why? Most companies are requiring auto formatters these days, so it doesn’t really matter if you can’t precisely align code.

Really? I've never used an autoformatter for anything ever, much less had one required. Which companies are these?

Google (I think they started the trend with Go?), Facebook, Amazon, … which companies “don’t” require auto formatters would be more interesting and specific.

Google leaves that as a team preference. Go certainly has highly opinionated style enforcement, but it is surprisingly not automatic formatting across the board.

Amazon may have changed, but this is also not universal. Team preference, though they may be enforcing it in the older code base for the site (i.e. detail pages, etc.).

Facebook is the only one on your list I can confirm does, in part perhaps due to the predominant language (Hack).

I'm curious what line-length limits these company's have (either imposed by an autoformatter or imposed by informal means).
