DSPs Decline Watchdog Platform Access Over Supply Concerns
Check My Ads, a nonprofit programmatic watchdog, sought buy-side (DSP) seats to run test campaigns and research programmatic buying but was refused access by multiple DSPs after initial interest. One unnamed DSP signed a master service agreement with Check My Ads and waived minimum spend, then later rescinded access citing concerns about protections for its vendor and supply partners. Another platform, Thrad, also declined to launch Check My Ads campaigns after flagging sensitive targeting and other setup issues. Check My Ads says the refusals conflict with the industry’s stated commitment to transparency and continues to seek DSP partners willing to support its research and small-advertiser services. The article was published and updated on 2026-07-23.
Shows practical limits to DSP onboarding and transparency commitments, with implications for watchdog research, programmatic auditing, and small-advertiser access; notable but not industry-shifting.

Rivals Pitch Transparency After The Trade Desk Audit Row
Following an audit dispute between The Trade Desk and Publicis Group, competing DSPs and ad tech vendors have stepped up outreach to media buyers, emphasizing transparency, product features and alternative CTV inventory. Responses range from sales pushes and LinkedIn ads to specific product moves: Nexxen launched an updated UI with multiple AI agents (open beta in March) for pre-campaign QA and optimization; Amazon announced partnerships with Comcast, Tubi and Samsung to extend streaming inventory via its DSP; Yahoo is hiring for AI-powered buying and planning roles. Buyers and mid-market agencies interviewed by Digiday say outreach has produced curiosity but little immediate roster-changing activity, viewing the holdco dispute as primarily about margin and control. Some smaller vendors, including blockchain-enabled Blockboard, report renewed inbound interest and trials, but agency buyers remain cautious about switching DSPs solely on transparency claims.
Buyers Rank DSPs as Competition Intensifies
Digiday surveyed 13 media buyers about demand-side platforms (DSPs) and produced a scorecard focused on DV360 (Google), The Trade Desk, Amazon DSP, Yahoo DSP, and StackAdapt. Buyers ranked platforms across transparency, data/targeting, inventory access, price performance and UX/support. The piece highlights an intensifying competitive dynamic — Amazon pressing The Trade Desk, independents pushing for share, and DSP vendors integrating agentic AI into workflows. Buyers prioritize CPM, log-level data access and streaming partnerships over vendor theatrics or AI marketing narratives. The article reports aggregated scores for each DSP and calls out recent platform moves: Trade Desk’s commercial and product challenges, Amazon’s DSP redesign and commerce-data advantage, Yahoo’s investment in agentic media tools, and StackAdapt’s UX strengths and OpenAI-linked inventory access.
US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
