Not all shelters are created equal. "There are two main sources of funding for animal control: your local government (tax dollars) and third-party donors (grants, foundations, and donations)." How much you want to bet that special interests like big pharma and technocrats are behind micro-chipping, forced sterilization, and vaccination of animals? It just my opinion based on observation, but I do believe that the animal experimentation has gone far and wide for decades and basically amounts to experimentation as a precursor to chipping, tracking, disrupting the fertility of humans.
