> OpenWrt is a great piece of software(firmware) to prevent ISPs selling your browsing data to the advertisers.
replyHuh, how? Either ISPs are doing deep packet inspection, and can track your browsing data regardless of what firmware you run, or they don't, and it still doesn't matter what firmware you use on your switches/routers, you ISP still won't be able to see TLS traffic, which most internet traffic is today.
How does deep packet inspection work on encrypted traffic?
replyUntil there's more wide support for Encrypted Client Hello (ECH), the SNI header in the TLS handshake is always sent in plaintext. Between that an unencrypted DNS, most routers can easily spot/log what you're accessing in a browser.
