As I also said, using the software is tacit support. It’s not possible to steal the design and reject the doctrine. If you use firefox or libreoffice you support mozilla and or the document foundation. If you drive a tesla that you bought second hand you support Elon Musk

By that logic if you use any firefox derivative like Waterfox you also support Mozilla. So by using any browser in existence you support either Apple, Mozilla, or Google…

If you buy a Tesla second hand yes, you are supporting musk, because you increase the demand for his products. That is not the same for free products in open source software. It’s especially not free for downstream consumers. Increasing usage of Waterfox will actually decrease usage of Firefox and cause Mozilla to struggle. There’s no payment or replacement of a fixed good that needs to occur. Your logic is very off here.
