Would you eat something where you don’t know whats inside? For me its like going into a Restaurant and they promise you it will taste wonderful, without telling you whats inside, only showing how it looks from outside. Would you eat it? That’s kind of what a proprietary emulator is for me. And I don’t have much to choose from, unlike vegetarian food (you can even make your own food out of the parts you buy). Sometimes I straight up have no other choice than use proprietary software (like Steam for Steam games, even the games are proprietary…).

I understand the nature of your comparison. We are making a compromise and accept that we have less to choose from, for our greater good and goal.
