ProPublica

Microsoft ended China-based engineers’ technical support for the US military after a July 2025 ProPublica report raised security concerns.

Who they are

ProPublica appears in this coverage as an investigative news organization whose reporting scrutinizes technology platforms, advertising systems, public-sector security and the effects of platform rules; it also operates projects such as Politwoops, which archived deleted politicians’ tweets.

The recent arc

The most concentrated recent phase was late 2022, when coverage paired ProPublica’s investigation of Google’s Display Network with its decision to set aside and seek to return $1.6 million from the SBF family foundation. The Google report focused on an ad network that could place advertising alongside pirated content, pornography and disinformation while allowing site owners to remain anonymous.

Since then, the arc has shifted from platform-accountability investigations toward cross-border security and influence reporting. ProPublica reported on the Terrorgram Collective’s grooming of a teenager in Slovakia, and on US diplomatic pressure around Starlink licensing in developing countries. Its July 2025 reporting on China-based engineers supporting the US military produced a tangible response: Microsoft said it would stop the practice.

The tension

A recurring tension is between the reach and opacity of major digital systems and the ability of journalists or users to audit them. ProPublica’s reporting has examined Google ad delivery, Facebook Marketplace and ad-targeting practices, and unlabeled state-sponsored YouTube channels; meanwhile, Twitter’s loss of the tools Politwoops required shows how platform control over access can constrain independent monitoring.

Why it matters

If this trajectory continues, ProPublica’s significance will lie not just in documenting harmful platform practices but in connecting technology operations to public accountability, from discriminatory ad systems to national-security exposure. The Microsoft response suggests investigations can compel operational change, though whether comparable pressure produces durable transparency at Google, Facebook and other platforms remains uncertain.
