No need to be rude. I know what scummy means. It's just not clear to me why this is considered scummy. Anyone is welcome to take the open source and benefit from it as long as they comply with the license. This is a very fundamental aspect of open source.
A company invests money and engineers in building commercial tooling, which you then pay for because there is added value. You are not paying for the open source - which is freely available. How is that scummy?
