Instead of spending engineering time, they used a free and open-source library to do less work. The license they agreed to in order to use this library has this in capital letters. [THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND]. After agreeing to this license and using the library for free, they charged people money and sold them a service. And when that library they got for free, which they read and agreed that had no warranty of any kind, had a software bug, they wrote a blog post and blamed the outage of their paid service on this free library. This is not another open-source project, or a small business. This is a company that got billions of dollars in investment, and a lot of income by selling services to businesses and individuals. They don't get to use free, no-warranty code written by others to save their own money, and then blame it and complain about it loudly for bugs.
