A lot of computer magazines, and some gaming magazines have a 'helpdesk' style column where you can write in to get help. some then contact the manufacturer and try to sort it out and print the results.
If you have this problem, write a coherent and 'professional' sounding letter to all of the magazines. This is the sort of thing that needs to make it into the general media if anything is ever going to change.
MS doesn't like to see a letter that hits a readership of hundreds of thousands that mentions their hardware is unreliable *and* they screw you on purchases made from them.
Personally, I have bought a lot of stuff off live. I have to play it all offline as I cannot get broadband at my house. I take the console into work after hours to download any demos and games etc. about once a month or so. but the last thing I bought was space giraffe, when I started hearing about this DRM issue I can't take the risk of spending any more money.
Not all of us can be online just to play. Even if you can, you shouldn't have to, and if you're taking your xbox around to a friends place it makes it a total PITA if you have to be online to use what you paid for.
It stinks, it is un-necessary and I think should be illegal under consumer law. take it to the magazines, the papers, your local consumer action group, and tell anyone that will listen, and let MS know that you have stopped purchasing content because of it.
I've been an xbox fan since I bought an XBOX1 release console, but although I love the games on the 360, I'm on my third paid for 360, and this will be my last MS console, and when it dies, I won't be buying another, it and the games will be sold.
I'm done with this.
