I wish these articles also included the fact that other large tech companies are and have been doing this since around 2019.<p>CloudFlare as an example detailed this letter in a blog post in mid-2019 which also called out the 36 companies. CloudFlare then went on to implement the CSAM hashing tool in a blog called "Announcing the CSAM Scanning Tool, Free for All Cloudflare Customers" in December 2019. This was also discussed and applauded in HackerNews a few years ago.<p>See: <a href="https://twitter.com/mhkeller/status/1196818679683530752" rel="nofollow">https://twitter.com/mhkeller/status/1196818679683530752</a><p>Other large tech companies have something similar for a number of years. Apple have clearly been put under significant pressure about this. In more recent news, OnlyFans was under pressure from payment processors for not detecting CSAM content on their services, which is why they were removing adult content.
