This is an awful take. No one cares who you are, first and foremost. 95% of users here aren't people anyone thinks about outside of this site, and probably not even outside of this thread. Don't go thinking you're some special case. Secondly, is it right? Legally, only. Morally, fuck no. While TheIsoZone was not taken down by Nintendo, their host was intimidated by Nintendo's takedowns, and other DMCAs from numerous other companies at that, to the point that they're now moving the site somewhere else with new links, the point remains that Nintendo is going after sites that have more than just Nintendo games. There's shittons of alpha, beta, unreleased, and abandoned games on these sites, and for many, these are infinitely more interesting than any dumb Nintendo game you can usually buy on the e-shop.
Get off your high horse, acting like you're some saint in a sea of moral degeneracy. I can defend piracy, because the EU released a 300 page study that shows companies like Nintendo aren't affected by it in the slightest, and that it helps with preservation. If not for piracy, the west would likely not be exposed to characters and media like Nosferatu, and thus the Dracula mythos. This means we also wouldn't have game series like Castlevania, or vampires in popular roleplaying games such as D&D, The Elder Scrolls, and so on. Piracy can bring great things for performance in games, where the DRM is too intrusive, such as that one Ass Creed game, or it can allow you to *actually fucking install games* in the case of Civilization 3, which is next to impossible to install today, because the DRM will refuse to let the game load solely because it refuses to run on any systems with virtual disk software.
TL;DR There's great things to come with piracy, and the negatives are greatly overstated. Get off your high horse. You're not a saint, just pretentious.
