You are missing the fact that Enfield council has RTB House , Criteo retargeting , Tru Optik demand side platform , OpenX , Districtm, msecnd , doubleclick , omnitag integrated as 3rd party. This doesnt make sense if the intent was purely to show internal ads. The implementation here seems to be no different to any other news site. As a visitor to the council website , I would expect that the same privacy levels and UX as that of gov.uk sites.
GDS are bringing them together, slowly... I recently applied for Personal Independence Payments (PIP). And despite being a new 'system' plus the assessments are carried out by two large IT outsourcing companies (Capita & Atos). It is entirely paper-based (drive.google is blocked, they don't take emails...). If you request a copy of the report they photocopy the physical file and post it. They are so backwards it is unreal.
Plus there's no provisions for an alternative format to the 30 page paper form. Not very independent if handwriting is an issue (the target demographic is people with disabilities).
Don't get me started on the actual assessment/ assessor. (it's been a long day going through this stuff).
