When working for these companies, have you ever asked if you could contribute back? In the field of pharma, a lot of contributors to RDKit discovered that no one had ever asked before. It now has a lot of contributions from people who work in industry. And don't fool yourself that GPL means companies cannot use it or include it in their products. Many do, even following the letter and spirit license agreement. As a quick example, OpenEye released openbabel under GPL; now their biggest competitor, Schrodinger, uses openbabel in products with the modifications released as a fork on github where the product is developed[1].
