I'm just not sure how worthwhile it is to hold them up as a particularly immoral player in the industry. Obviously them taking out yuzu and citra is shitty but is that really so aggregious compared to the shit that they and the other major companies pull all the time? The rampant exploitation of workers at the software, hardware, and material levels? Everything to do with Microsoft?
I'm seriously not trying to say that it's stupid to criticize Nintendo or to not buy their products. I do not care what video games you buy or do not buy. I'm not interested whatsoever in convincing you that you should be handing your money to any international corporation. I just think it's maybe worth stepping back a bit to look at the bigger picture.
Does Nintendo have a particularly aggregious record of going after emulation and people that participate in it? Absolutely. But I don't really think that's due to anything other than Nintendo being more heavily impacted by emulation (at least in their own view) than any of the other major publishers, and I don't think that's really the heaviest ethical issue weighing on the industry as a whole, either.
