Companies can and do ship low quality because when you do the cost-benefit analysis, it makes sense to get it out the door, warts and all. Also, when a company gets large enough, basic things like this fall through the cracks because everyone is tasked with their small part of the project, and likely no one person was in charge of getting the load times down, or else they were and the load times were within “acceptable tolerances”. Maybe they even created a JIRA ticket to track the work to fix the load times, but once the product shipped, the priority of that worked dropped and it was never looked into again.
