FOSS in programs and appliances are OPEN SOURCE for a reason, consider many to be ‘models’ used to build upon. Your reason’s are factual down to the specific applications/programs however try appending a new function in MSO or adding your on embeddings in Adobe to change the scaling. For those looking to make their programs work for them and have some experience in programming and time, FOSS is perfect to do so, others that use these apps and haven’t the time to dedicate to customize features, import their own libs and assets and don’t mind paying for it, indeed that may be the better option. 🐈‍⬛
