Spot on Josh! I think many long term hearers do come to the conclusion that ignoring the pest is good practice. I also remember occasional discussions along the lines of if this intrusive nature is in any way being used wrongly by those with agendas on mind control stuff. [Which one can't dismiss too readily.] This then leads on to the black agenda list as to whether there are moves to destabilise any research into how hum affects us out here. I've no doubt whatsoever , that this a possible- and due to factors as simple as HAARP,Tetra , Broadband. Power lines, Gas pipes, Motorways et al which just 'growed like Topsy' all over the place for 100 years now. Society is getting ever more controlled, but also litigatious- and money talks [or maybe - HUMS]
