It's a holiday week in the US. Most people aren't even home here right now. It is the single biggest travel day out of the year. Plus, globally, not everyone is glued to the FDev forum for up to the minute news at any time, let alone a holiday season.
More than even that, many were planning on using the Christmas holidays to update or build a PC - which is still a month away.
Giving only 6 days notice that console games will become virtually obsolete, after just stating two months ago that they would not, is beyond last minute warning. It is entirely reasonable, that a quarter of their player base should be afforded more than 6 days notice. Especially when they can't even decommission their carriers in that time.
It's really not difficult to understand.
