Start treating the adtech industry as a national security threat. U.S. Central Command has confirmed that adversaries are using commercially purchased location data to target and surveil American military personnel on the battlefield. That's not a hypothetical risk — it's happening right now, and the data pipeline fueling it is entirely legal. Location data flows from our phones through online advertising ecosystems, gets packaged by data brokers, and sold to anyone willing to pay. Foreign adversaries are buyers. The same warrantless data market that tracks consumers for ad clicks is actively being weaponized against U.S. troops in theater. Senator Ron Wyden has already called this out directly. Now Congress needs to act, not just acknowledge the problem. Pass legislation that treats the commercial surveillance industry as the national security liability it is. That means restricting the sale of location data to foreign entities, regulating data brokers, and closing the loophole that lets anyone — including our adversaries — buy what a warrant would otherwise require.
