"Would Britons be required to avoid software from creators that fall outside of the UK’s jurisdiction? Would visitors to the UK be expected to replace the software on their laptops, and have all messages to and from the UK be scrutinised by the government for contamination by encryption?"

So what would actually happen would be that the law would be enforced only for people whom the government dislikes - e.g. investigative journalists or political activists. It's just another pretext on which to lock up inconvenient people.
