There was a time when I was okay with just going along with their erm... let's say 'direction' ... but it absloutely flooredme when I realisedI could no longer set up a network using manual details any more and the only way to get it to work was by using their DHCP, which (and I am struggling to recall how exactly they did this) effectively bypassed all attempts to secure my network connection... I know what I am doing with networking and it was just surveillance coercion!
