That I do not disagree with.  Once they stated that only one machine can have access to the library at a time, I knew it was only going to be useful to a small subset of users.

He put a link in "legally entitled" for a reason.

I have to agree with the OP, it's a rubbish policy that punishes legitimate customers. If the Steam people want to limit games to 1 instance per account they have the power to do so, but the blanket policy in place today needlessly hobbles the sharing feature. I suspect that these anti-consumer limitations were put in place at the behest of publishers, as is so often the case with any sort of digital media.

I think the issue here is that Steam released a feature that isn't useful for the vast majority of its user base. The only reason this feature is useful is so you don't have to give the person the password to your steam account. So rather than "family sharing" it works as "stranger sharing"

If you trust the person with your account password, it is much better to let them use steam in offline mode (and disable family sharing). That is similar to what I do with my dad (we live in the same house). I login for him and download games for him to play, then he stays in offline mode after that. I have zero problems with this method, and I am grateful it is possible.

Bottom line is, if you use steam, you can't complain. If you don't like steam, STOP using it. Steam will only continue to act as it is so long as people are willing to pay for it.

As for me, I only have 2 games on 2 separate steam accounts. This way I can play either when I want and IF steam decides to lock out one account, I don't lose my other game. However, even with all this in place, I find steam WAY too frustrating to use; forced updates, crashes, an ever changing EULA. It's really not worth my effort and I doubt I'll ever buy another game off of steam so long as they continue with their current business model.

Yes, I miss out on some gaming opportunities....but there are plenty of games out there to play.

Would you prefer no family share? Cause thats the other option.

While I doubt that this will spark a mass exodus from Steam, your logic is wrong.

One option is to choose not to use the family share option. One option is to go offline as needed to allow both to play at the same time. Another option is to express dissatisfaction with Steam's service.
