Steam

Nor do I even have to be the one to come up with a plan.

People that just complain without a better improvement in mind didn't actually care to change anything, because they've haven't shown that there's a reasonable alternative. Those people don't care if there's a practical alternative, they're just upset that it doesn't meet their specific needs. They just want to "speak to the manager" and complain. "It's not my job to fix it! Fix it!". If that's quote captures your stance, just lmk and it will save us both some time.

I actually even already gave a simple plan and you ignored it.

I didn't ignore it, I asked how it would deal with a fundamental enforcement of rules that steam has always done and you've ignored that, lol. Are you here to just complain or do you actually want to see if there's a better way forward? What's a feasible alternative to handle hackers and provide quality of life improvements like family sharing?

Your arguments that hackers are more important than a parent with a kid are selfish and stupid.

I'd argue that hackers are more important to valve because they implemented VAC bans almost 20 years ago. They just now announced a family sharing feature and you're pretending that steam was meant to be designed around the family to start, which is an uphill battle to argue.

And force Valve to ruin it for the rest of us.

First of all, it's already implemented this way. You're the one arguing for an alternative that could increase the number of hackers - if anyone is trying to force valve to ruin it "for the rest of us", it's you, since you're arguing to change the status quo.

Finally, don't want valve to "ruin" it for you? Don't use the brand new opt in feature. You have lost absolutely nothing - nothing has been "ruined".
