Note that since recently some cheaper providers (especially UPC and its sub brands) have switched to CGNAT, which does not support port fowarding as your modem does not get its own IP assigned. I have been always happy with iWay, Init7 and Green.ch. they are only slightly more expensive (except Init7) but their service is awesome and super nerdy :)
Because I am not sure if I want a 3rd party “controlling” my trafic. It sucks that my behavior is shared around in ad networks but I am not sure if the ad blocking components are more trustworthy. There are certainly good solutions out there but I am sceptic of the explosion of new ad blocking tools. Having said that, I never did a deep research to check if my scepticism is justified…
