> Charging for a commercial license is virtual closed-source. You have reinvented selling software, except with a “try before you buy” model that enables engineers to vet its utility first before paying, with free usage for non-profits (i.e. other non-profit devs).

You really do not understand what rights Open Source licenses give you. The GPL in particular really only affects you if you distribute it (a js library vs nginx). There is no 'non-profit' exception in the GPL.

Every software company has a license that governs it's use. I am pretty certain your company will use legal threats if it's source code got out or it's frontend code was being abused. There are likely legal clauses in your employment contract over the source code that you have signed.
