The same reason why people use joke languages like Rust and retarded frameworks for example Electron: Most people who develop software (malware in many cases) are not very good at making software, or they are good at making software and have passion for it but are so pushed for time because of stupidly tight deadlines or constant changes to requirements by clients/management that they are forced into writing nightmare garbage code and using whatever bullshit will get something looking close enough for as little effort as possible.

The former is especially problematic. A surprising number of programmers don’t have a whole lot of passion (especially those writing corporate programs, understandable really) for writing good software (by “good” I mean software that is not only fast, reliable and beautiful to the user but also elegant to the engineer), which causes a lot of bullshit.
