Personally, I encounter long functions (as you described, around 100 lines) mainly in older codebases that were written over 20 years ago. In many cases, I get them for rework when developing new software, particularly in industries where the adage is 'if it works, don't change it.' This phenomenon could be attributed to the fact that, at that time, OOP was just emerging, and developers were not yet accustomed to it. I strive to write code that is concise and highly readable. It's important that the function's purpose and usage are immediately evident at first glance, rather than relying on copious comments.
