Security Roundup: FIFA Auth Flaw, Chrome Adblock Changes, DeepSeek Holdoff
A Dev.to roundup (published 2026-06-17) highlights three security and privacy stories: a reported authentication/authorization vulnerability affecting FIFA World Cup systems (source: bobdahacker.com); Google Chrome’s Manifest V3 update that further restricts extension capabilities by deprecating the webRequest API, undermining many popular ad and tracker blockers (source: 9to5Google, June 15, 2026); and Reuters reporting that the U.S. government has delayed blacklisting Chinese AI firm DeepSeek while identifying over 100 firms as national security risks, underscoring growing AI supply‑chain security concerns (source: Reuters, June 17, 2026).
Google's Manifest V3 platform change is a major browser policy/technical update with direct implications for ad blocking and browser privacy tooling; combined with national-security scrutiny of AI vendors, the items materially affect privacy, identity, and supply‑chain risk in the ad/tech ecosystem.

Week in Review: FIFA+ to DAZN, BBC Shorts, EU Concerns
This Week in Review covers multiple media and ad-tech developments: FIFA+ will be integrated into DAZN and the standalone FIFA+ app will shut down, creating a larger global football offering. The BBC has added swipeable short-form feeds to its News and Sport apps to compete with short-form platforms. Forty-six ad-tech companies signed an open letter urging EU policymakers to scrutinise proposed Digital Omnibus Articles 88a and 88b, warning the measures could shift privacy choice management to browsers and increase legal and technical complexity. Industry product and M&A moves include PubMatic launching Decision Fabric to run partner decisioning models inside auctions, YouTube earning MRC brand-safety accreditation for Shorts, Peer39 acquiring Adloox, and Lumine Group acquiring Synamedia’s Video Network Business. The roundup also notes publisher, agency and hiring news across the UK and global markets.
B2B Advertisers Must Embrace the Weekend
Bloomberg Media's David Bradford argues that B2B advertisers are missing opportunities by confining their campaigns to the working week. In a world where work and life blur, decision-makers are always 'on' but in different mindsets, especially on weekends. Bradford highlights Bloomberg's Weekend proposition, which offers in-depth, reflective content that attracts a growing audience of leaders. He cites YouGov data showing Lenovo's successful B2B activation during the World Cup, demonstrating that broader placements can work. He encourages advertisers to follow audiences across premium environments like podcasts, LinkedIn, and OOH, reaching them when they have more space to think. The article is an opinion piece advocating for a shift in B2B media planning to include weekend placements as a prime-time opportunity.
Ecosia Drops Mistral for Chinese Open-Source AI
European search engine Ecosia has switched its AI supplier from French startup Mistral to open models, including Chinese ones like Alibaba's Qwen, Z.ai's GLM, and Moonshot AI's Kimi. CEO Christian Kroll cited disappointment with Mistral's model quality, which he says lags about a year behind competitors, and frequent server overloads. Ecosia now uses models via German platform Melious, which runs open AI models on EU servers, halving AI service costs while improving performance. The switch comes as Mistral released Large 4, its most powerful model yet, trained in Europe with open weights due in October. Despite scoring 38.4 on the Intelligence Index, it ranks eighth among open models, behind seven Chinese models. The case highlights the European AI sovereignty dilemma: top-tier open models are predominantly Chinese, even when run on European servers. Mistral itself hosts Chinese models like GLM on its neocloud platform, while its CEO Arthur Mensch defends Large 4's capabilities in areas like cyber defense.
