I think that's Google hemartia. They execute really well initially, but falter on maintaining and nurturing ideas and products. The internal incentives regarding promotions and pay amplify the problem. Maintaining or improving a product isn't as impactful to one's career as creating an entirely new one. They have a half dozen chat apps because they unintentionally created an engineering "crabs in the bucket" situation. Not to say they are anywhere near as bad as the companies who do it on purpose a la stack ranking though.
