This stems from the fact that many in web dev are not really engineers. There’s a lot of reinventing the wheel and cult like following of various tech influencers. Instead of extending existing libraries people just fork repositories, add minor changes, and advertise them as new. A lot of architectural patterns are just a soup of concepts thrown around without proper planning or understanding of dry or solid.
A big problem is for anything to be successful it had to be similar enough to the last thing. E.g. all the new frameworks that look and feel like React. Every new thing is constrained and sticky taped onto the older thing. So no one can ever step back and ask themselves what the truly ideal thing is.
