I’mma wax philosophical for a second: I love the open source nature of the First Responder Kit because it lets anybody, anywhere, diagnose database problems faster. If you’re a full time employee somewhere today, you owe it to yourself to use the FRK scripts because if you ever switch from one company to another, your employment agreement will probably require that you leave your old scripts behind. (I’ve actually been involved in a lawsuit where a DBA took his T-SQL scripts to his next job, and got sued for it.)
Someday, I hope you celebrate your own personal independence and
