I've decided to write about the work our team is doing regarding open-source projects. I will give a list of open-source projects we have checked by now with the PVS-Studio analyzer. Then I'll tell you about our plans for the future. We are friendly to open-source projects. But don't forget that the "open-source" status of some software doesn't necessarily mean that it is being developed solely by some enthusiasts for the common good. Many projects are developed by workers of large companies, and they are paid salaries for that. People sit in their offices, eat cookies, do programming, and write articles about advantages of open-source software.
