We have data protection laws. The ISP can&amp;#x27;t just sell browsing data. That has been illegal since before we had data protection laws, that is actually legally the same as opening other people&amp;#x27;s letters and reading them. So ... different threat model over here.&lt;p&gt;I am always using the US-EN Firefox version because frankly why would I use translated software when I can understand and use the original.&lt;p&gt;I hope you can see how it might be of concert to me whether Mozilla decides to give my browsing data to Cloudflare, whom I have about as much reason to trust as GCHQ or the NSA.</text><parent_chain><item><author>badrabbit</author><text>Your ISP is literally selling this information right now in the US.
