oh, well yeah, I'm not arguing that they have any legal obligations. It's their software and they can do whatever they want, I guess. I'm just saying that given how ubiquitous xp still is, especially in the business and educational worlds, it seems irresponsible to just give up like that.
And to their defense the hole is a lot less severe on xp due to the windows firewall. But still--if I was a sysadmin at a company or a school I'd be very mad that my "supported" systems had an unpatchable security hole blocked only by a stopgap solution.
Nobody knows for sure, but I have to say, I don't think MS just gave it up on a whim. If MS is not going to fix a problem with XP, I believe they have a good reason, personally. A LOT of people are going to remember this and use it against MS for a LONG time, I don't think MS would risk that unless there was an excellent reason. It's not like Win 7 is getting bad reviews and MS is desperate, but maybe they are, I just doubt it, at this point all we can do is make baseless idle speculation out of it.
