"High performance has shifted into how fast we can serve bloat."

If remove ads and behavioural tracking, speed is faster

But goal of Big Tech, who make the popular browsers, is to make speed faster (fast enough) _with_ ads and tracking

User wants fast speed. User does not want ads and tracking. Big Tech wants users in order to target with ads and tracking. Big Tech tries top deliver fast speed to keep users interested

User can achieve fast speed _without_ ads and tracking
