A bit of both, I believe.
I've heard of many companies having 'consulting bans' in place before, even during normal times; however they tend to be gradually forgotten within the course of a year. A certain large UK telecoms firm which is reknowned for keeping the entire consulting sector afloat appears to put these in place regularly and then ignore them with equal equanimity when it turns out they lack the ability or will to do anything by themselves.
Siemens, on the other hand, is a fairly well-run and boring firm who are likely to keep this one in place with solid, teutonic determination. We shall see.
