Monocultures are known to be points of failure, but people keep going down that path because they optimize for efficiency (heck, most modern economics is premised on the market being efficient).
This problem is pervasive and effects everything from food supply (planting genetically identical seeds rather than diversified "heirloom" crops) to businesses across the board buying and gutting their competitors thus reducing consumer choice.
It's a tough problem akin to a multi-armed bandit: exploit a known strategy or "waste" some effort exploring alternatives in the hopes of better returns. The more efficient you are (exploitation), the higher the likelihood of catastrophic failure in weird edge cases.
