Controversies and Legal Challenges.

1. Content Attribution Controversy (June 2024).

Perplexity AI came under scrutiny after Forbes and several other media organizations accused the platform of republishing summaries of their articles without proper credit or permission. The core of the controversy revolved around whether Perplexity’s AI-generated responses constituted fair use or unauthorized content scraping.

Critics raised ethical concerns about intellectual property rights and transparency in AI-generated content. In response, CEO Aravind Srinivas publicly addressed the issue, reaffirming the company’s commitment to responsible AI practices. Perplexity soon rolled out updates to improve content attribution, including:

The case is currently ongoing and could have broader implications for:

• Naming rights in the tech and AI industry
