Your rock analogy is not just silly, it is stupid.The whole point of my posts is to find/share third party information about TLS, which is sorely lacking. That appeared to be the purpose of the OP as well, in order to make an informed decision about the value of their service. One thing I find interesting is that according to some accounts, CHL instructors who allow TLS to give presentations get a slice of the fees. Now, I have no problem whatsoever with such arrangements, but I do have serious issues with it not being disclosed. To me, that is a breach of trust and a conflict of interest. Of course, it's legal to do so, but it certainly calls into question motivation.
I'm not trying to convince anyone to do anything. If paying your annual fee makes you feel good and gives you peace of mind, then great, have at it. I also wouldn't try to dissuade someone from using their tiger-repelling rock: if it makes you feel good and you find value in it, go for it. After all, nothing is worth anything but what someone is willing to pay. Those on the fence about such a service may find some of my observations useful, if only the counter replies.
