You’re fucking with me now, right? Had you never heard someone tell you that life isn’t black-or-white? Had you never seen a switch use a black/white, opaque/clear, or smooth/textured to indicate on/off? The only way I could see blacklist/whitelist being confusing is if you’re uncertain about the context that it’s being used in, but allowlist/blocklist is going to be confusing in that regard too. What’s being allowed? What’s being blocked?
