I haven't changed my tune - the two scenarios are completely different.
In the Phorm situation, citizens' communications were being intercepted, copied, scanned and then the content of those scans used to profile individuals behaviour. It was active surveillance over which the citizen had zero choice or control.
In the adblocking scenario, communications are scanned for specific patterns which only match advertising code. The content of the comms is not copied and used for profiling behaviour and the citizens has to opt in to the service (if they don't their comms bypass the tech).
Another big difference between the two is in the Phorm case, all parties in the communication were likely to object to the interception. However, in the adblocking case, publishers have a vested interest in not consenting to the activity because they benefit from the ads being blocked.
With the privacy and security issues surrounding programmatic ads and privacy being a fundamental right under European Law (Article 8 of the Charter of Fundamental Rights of the European Union) it is absurd to suggest that publishers should have a veto over a citizen's choice to block ads.
Furthermore, I haven't changed my tune - I have not stated that RIPA doesn't apply in the adblocking case - I have been actively lobbying to have EU Law changed to remove the all party consent requirement for situations where ISP customers have explicitly requested a service (opt in) and I still fully support the prohibition of arbitrary blocking imposed by the ISP without the explicit opt in consent of the customer.
I find it amusing that some people think I need reminding of what I wrote - I don't, I wrote it. I also find it strange that certain people think I have no right to have a different opinion in different situations - the Phorm case and the adblocking scenario are opposites in many respects and it is entirely my right to have a different opinion on both scenarios.
