Yahoo got into a lot of PR trouble (and some Congressional scrutiny) a few years back for its cooperation
with the Chinese government in handing over info on some users. Folks at Yahoo have certainly suggested in the past that this was a mistake on the company's part, and it looks like it's acting differently this time around... in Belgium. There, a court has fined Yahoo for failing to hand over information
on a user accused of illegal activities. Yahoo's response is that, as a US company, all such requests should go through the US. This makes a lot of sense for a variety of reasons (otherwise, Yahoo would be responding to requests from tons of different countries), but many may cynically point out that Belgium is a much smaller market to "fight" than China. On the whole, though, it seems that Yahoo is making the right move. If the data was being hosted in the US, then it only seems reasonable to suggest that the data is under US jurisdiction, not Belgium's.
