Companies build software to meet their daily requirements and targets. According to a study, there are about 190+ companies globally, but most of them aren’t in shape to contribute code and have open source. But to be sustainable and to experience customer-friendly open source, companies need to build software. The more software is produced to meet the need of consumers, the more updated the software would be. Thus, we would be least worried about sustainability

Companies focus on providing value to customers globally. The requirements that the companies have, the software are built to meet those requirements. Companies like Walmart, Lyft, Airbnb, etc. are fortunate to use and create open-source software.
