It's a trap.

Remember they're not ever going to stop you from purchasing multiple copies of the game. They will and have been increasingly more intolerant of playing them simultaneously.

The day will come where they won't let you use two at the same time, ever and you will have serious regrets about the time and money you continued to pour into it. They are not obligated to honor their past agreements. To the contrary 2013-2020 shows this.

I believe this is why they used weasel words. Think about it. If they're not alright with software multiplexing why would they be fine with hardware multiplexing? It's the same thing. It just allows them to keep siphoning money off of people they clearly don't want around.

The sooner you all realize this the better. Like me you have more disposable cash for your hobby than most do. Put that to good use. Hurt them financially by not supporting them. Let the company know that you won't be suckered again.
