Your comparison is still really, really unclear. Are you comparing the consumption of "extra products" for vegans vs vegetarians to the consumption of "extra products" for piracy?

If so: Do you really not understand that limited physical demand differs from unlimited digital demand? If a vegetarian eats, idk, an egg a day.... that's an extra 365 eggs that had to be produced and were paid for, thus supporting the industry, when you could have hypothetically decreased demand and possibly caused a drop in production. Whereas the media consumed by pirates incur neither profit nor cost (in that if we assume they would never have paid for those goods in the first place, it isn't a lost sale). There is no production cost for there to be 1 sold copy and 1 pirated copy vs 1 sold copy only.

Though tbh, I'm just devil's advocating the vegan position here. I really think you had a handful of bad encounters with militant vegans and assume the majority of the threadiverse thinks like that. And, well... we don't? What even is this "lemmy culture"? The amount of confusion and responses that aren't addressing the point you meant to make should show you that most of us are not engaging with this on the line of thought you assumed we would.
