There's a general "bad" when law are enacted and then not enforced, especially if it's a law that most people would naturally break because it's a silly law. It allows the authorities to persecute chosen individuals while not actually achieving anything that the law as written looks like it should be trying to achieve.
And this is a silly law. Everyone will break it, every time they use an encrypted communication, which is pretty-much every single thing one does on the internet these days. It's a perfect recipe for the authorities to let everyone carry on as normal, then when they want to crush someone they're certain to find some law that they have broken like this one.

The will get a prosecution after catching red-handed a mass murdering terrorist or a pedo with kids locked in their basement because they did an online shop which "used encryption". The authors will claim victory, without these protections we couldnt lock these people up, the Sun and the Mail readers will lap it up. 5 counts of murder and 1 count of doing an online tesco shop.
So years ago there was a corruption scandal in Brazil, where gambling is illegal. A guy named Carlinhos Cachoeira[1] found that fact a great opportunity and built a gambling empire, which involved financing corrupt politicians so that they would vote according to his interests. Among those on the payroll was a senator, Demóstenes Torres. Well, one day an audio of a conversation between Demóstenes and Carlinhos leaks. It went something like that:
Carlinhos: so I want you do vote in favor of [law X, which toughened restrictions on the kind of gambling Carlinhos promoted]
Demóstenes (naively): but, professor, that will make things harder for you, won't it?
Carlinhos: oh, don't worry, it's not going to be used against me.

We should be throwing out such laws.
