I'm going to guess that you're used to codebases that use an autoformatter.
There's definitely a case to be made for autoformatters in projects with a very large (>100) number of developers, but the price you pay for that is much poorer information density per screenful of code.
For things like tinygrad or sqlite with a small dev team it's possible to use whitespace, style, and formatting to communicate important information, just like mathematicians do. The AMS journals don't autoformat mathematicians' equations!
