The FDA’s regulatory process for the approval and marketing of drugs is a factor in how this disclosure system/mentality in pharmaceuticals came to be. U.S. drug companies cannot advertise drugs for uses beyond what they’ve been explicitly approved for. But doctors have the freedom to prescribe whatever they want — e.g. fentanyl approved for cancer-related pain could theoretically be prescribed by a doctor for migraines. The ostensible purpose of financial disclosure is to mitigate the problem of doctors being incentivized to prescribe inappropriate based on their ties to a pharma company.

Tech doesn’t operate under such strict regulation, e.g. Tesla’s Autopilot isn’t forced to issue verbose disclaimers like the kind you hear for a TV drug ad.
