After years of development and testing, Google has added Interaction to Next Paint (INP) to its trifecta of Core Web Vitals – the performance metrics that are a key ingredient in its search ranking algorithm. INP replaces First Input Delay (FID) as the Vitals responsiveness metric. This is what the INP metric assesses."

One could argue this is a metric-driven decision. When they dug into the data, they found that the reason load times had increased was that they got a lot more traffic from Africa after doing the optimizations. Again, it’s easy to fake performance optimization by leaving out the bad metrics, blocking users who spoil the stats.
