TechWARU's tools are all free to distribute and free to use in a commercial environment. But, those tools are a subset of the tools that you as a technician are allowed to use. The difference lies in both legal distribution and paid licensing.
Distribution: There are a few applications that we are not allowed to distribute but you as a tech are allowed to use.
Licensing: Techs can purchase paid licenses if they so choose and can add those paid versions to TechWARU. For example, SAS if paid for, can be added to TechWARU as a custom app and used commercially.
So in summary, if it is legal to use in a commercial environment, it is legal to use in TechWARU. We just might not be able to distribute it or the proper licensing.
