Are you full of shit? Their family sharing is the most locked down garbage there is, they limit you to families of 4 and make you wait a year before you can join another family. That's not a courtesy, that's a fake courtesy so they can say they provided something, and claim to be "good guy Valve", actually that's not true, they never claimed to be good guy Valve. It doesn't help that they made publishers able to mark games as not family share supported.

While they added so much to the Family share feature they also took away a lot and locked it down considerably. I'm not going to pretend the fancy new options and ability to add 4 accounts is an upgrade, you get locked out of it for a year if you join and leave and any publisher can refuse to participate.

Let us not pretend that Valve is somehow trying to do good, they're trying to make themselves look good while providing less, and when people point out the shortcomings they try to turn us against each other by saying it was "because of abuse", the real reason is because they don't want to give it their all.
