Yeah, but then both OP and The Verge wouldn’t have such a juicy headline for sick internet points and clicks.

It’s more accurate to say “~15,000 Roku users were hacked due to reused passwords”, and reusing passwords is one of the worst things you can do security-wise because if your password got leaked on one website (doesn’t even need to be the full password, just the hash would work), you are now entirely compromised everywhere you reuse that password.
