With them we are directing our attention to consent walls in the context of publishers and the open market, having already dedicated two recent interviews to the “consent or pay” model as it concerns Instagram and Facebook (ie. Meta). We will also try to understand the challenges and potential conflicts of interest faced by CMP (Consent Management Platform) vendors.

Robert Bateman: Consent or Pay
Robert Bateman is a data protection writer, trainer, and consultant. He has published innumerable articles on the topic, as well as led panel discussions and interviewed key well-known figures in the space on stage, at well-known privacy conferences. Besides freelancing as content creator, he is an associate with Act Now Training and a Subject Matter Expert with Heward Mills, a data protection consultancy. With Robert we have addressed the recent public outcry about Instagram and Facebook becoming paid services for whoever does not want to see ads or consent to the data processing involved in running them. Given that we have already got used to seeing cookie walls on European news websites (in Germany, France, or Italy), we have aimed to open the wider debate around “Consent or Pay” business models.

Cory Underwood: The new privacy landscape for US-based digital marketers
Cory Underwood is a Privacy and Data Analytics Engineer with a strong marketing data technology background and a good knowledge of both US and EU ePrivacy law. Cory supports the data privacy offerings of Atlanta-based Search Discovery (a data strategy and activation company), leveraging eight years of experience in privacy efforts and multiple privacy related certifications to enable clients to understand the impact of privacy changes. With a combined thirteen years of experience in technology, Cory specializes in speaking and writing on his blog (cunderwood.dev) about upcoming privacy changes, allowing readers to take a proactive approach to compliance challenges. In our second interview with Cory we have looked for answers to the following questions: What does it take for Digital Marketers to comply with State-level Privacy laws in California, Virginia, Colorado, and beyond? Will the US internet suffer the fate of European websites, annoying consumers with user-unfriendly consent pop-ups that mean little and cost millions? Why do some US websites insist on replicating the European ordeal if there are no opt-in requirements? What will be the side effects of large platforms adapting to the EU’s Digital Services Act in terms of transparency and return on investment for SMEs? Where will Topics API, the star framework of Chrome’s Privacy Sandbox fall in terms of consent requirements?

Katharine Jarmul: Demystifying Privacy Enhancing Technologies
Katharine Jarmul is a privacy activist and data scientist focused on privacy and security in data science workflows. She’s a principal data scientist at Thoughtworks and has worked at various companies in the US and Germany before that. She is also a frequent keynote speaker at software and AI conferences. Katharine has recently published “Practical Data Privacy” (O’Reilly, 2023), in which she provides a deep dive of Privacy Enhancing Technologies (“PET”), including detailed answers to increasingly common questions: How can we actually anonymize data? How does federated learning work? Can we already leverage Homomorphic Encryption to run analysis or work with data even while it is encrypted? How can we compare and pick the most appropriate PETs? Can we use open source libraries? In our discussion: Can we bring Privacy Enhancing Technologies down to earth for smaller companies to understand and apply them on a regular basis? Are they otherwise the monopoly of Big Tech, and does this mean that a company like Meta ends up becoming the unlikely poster child for Privacy by Design? Can we really speak of a common ethical framework for AI or GenAI? How does a US/Western Europe ethical framework fit within African or Asian cultures? Can we break the convenience barrier when it comes to individual control?
