Because Gui’s don’t show advanced options and so I know/understand exactly what is being done. (e.g. I would always use apt over mint’s package store so I could see what it did, how much time I had left, download multiple applications at once and see if the package made a random config file somewhere)
Tools for backing up servers already exist: https://github.com/Tyrrrz/DiscordChatExporter But unfortunately discord can’t be easily scraped in one coordinated attempt unlike reddit due to the massive number of private servers and existing verification/anti-bot mechanisms. As a result, only the communities that have data hoarders will be actually archived.
