It is very useful those apps exist. They also advertise the lack of ads in those apps so I suspect they are financed by some public (or charitable) institution. Unfortunately, all apps can't be finances this way so I personally would really like for some privacy minded ad network to appear. I suppose most people associate ads with no tracking/ids as useless (paying an order of magnitude less than the alternative). I wish some innovative method emerged to make privacy friendly ads have comparable sucess rates.
