I think the saddest part of the LLM infection of open-source software development is the loss of trust in each other. Beforehand, if somebody submitted some bad code, it could be assumed it was either a mistake or they weren't well-versed enough with the codebase. Nowadays, any code submitted by an unknown party brings immediate scrutiny and a "guilty until proven innocent" mentality. Its a valid defense mechanism, but I will never forgive the corpos for this.
