Recommending to host an exit node in Switzerland in the context of TOR feels like reading an article of someone who thinks they are anonymous by using TOR. Switzerland is even more privacy invasive than German laws, and that is the case since 2010 when automated connection tagging was introduced for VND and VÜPF.
Why even more? Germany also do's connection tagging, and additionally always thinks about to hold the transported data too (vorratsdatenspeicherung). The problem described here is that the possibility to have a entrance node and a exit node in Germany is really high, because Germany is the biggest provider in tor bandwidth.
