In life, nothing is perfect. For example, I can't use a CPU based on an open ISA as my daily driver. Does that mean that CPUs "don't work"? Of course not.
The fact that something is used for illegal purposes means that it doesn't work? Does LSD "not work"?
The fact that something is hard to set up or maintain mean that it doesn't work? Does Linux not work? Do airplanes not work?
Does the fact that something is an environmental disaster mean that it doesn't work? Do cars not work? Do highways not work?
