From experience I noticed that a lot of developers don't look at the big picture and don't have a full understanding of how the system works, what's the rationale behind how the feature achieved its objective and how it might be abused by a malicious user. The #1 thing that I think about when I'm looking at some code or feature (and recommend others do the same) is how malformed or intentionally malicious input would break it, but it seems like their developers clearly didn't do so.

This is also compounded by the drive to artificially complicate software stacks (microservices, etc) and "silo" developers into their own little bubble where they only work on a small aspect of the system and never have a need (nor the mental capacity - due to intentionally complicated stacks with dozens of microservices in various languages) to look at the big picture.
