This is not about facebook not hashing credentials, it is that they appeared in internal logs.
Facebook is probing a series of security failures in which employees built applications that logged unencrypted password data for Facebook users and stored it in plain text on internal company servers.
You are acting like someone checked off a "log passwords" box, as if that's a thing that even exists
Someone configured a logger to write HTTP bodies and headers, not realizing they needed to build a custom handler to iterate through every body and header anonymizing any fields that may plausibly contain sensitive information. It's something that literally every dev has done at some point before they knew better.

If you're working for a multinational tech company handling sensitive user data and still make this mistake, then you are being malicious in your incompetence. This is something that would cause you to lose a significant amount of marks on a first year college programming project, let alone a production system used by literally billions of people.
mod_dumpio allows for the logging of all input received by Apache and/or all output sent by Apache to be logged (dumped) to the error.log file. The data logging is done right after SSL decoding (for input) and right before SSL encoding (for output). As can be expected, this can produce extreme volumes of data, and should only be used when debugging problems.
I don't agree that this is "absolutely malice", it could also be stupidity and forgetfulness.
