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.
Regarding your point on not being able to be matched up against blocked players:
I would argue the opposite. Vermintide 2 employs this exact thing and it’s been working pretty well - it actually does punish people who get blocked a lot by other people, and if you’re being blocked by a ton of people, there’s probably more than just “skill issue” and “you’re not running meta” going on. You do get sweaty people who block non-sweaty people, yeah, but it’s not hampering the community of the game in the slightest - and that game is waaaaaay smaller in size than something like Helldivers where you can get blocked by a ton of people and still play with other people due to the sheer size of the playerbase.
