Without going into a pure political debate, if one followed the internal news in Sweden, this was not any sort of surprise. Sweden and China have had a long time beef and many times sadly behaved like small children. But what made me personal lift an eyebrow, was when the Post and Telecom Authority in the news/live yesterday state this decision had nothing to do with the technology, but everything with the country China. Apparently that is one of the main rules they can use against any outside company. Fair enough, but it also went straight against what the Swedish Security service and Armed forces said. Nothing Huawei can do about it anyway, but Sweden should probably not be surprised if it gets hit by restrictions in one way or the other.
The removal of Huawei within a few year I can guess will be a similar issue UK have. Not easy as just snap ones fingers as they are deeply rooted into both 3G and 4G.
