The biggest one that jumps out at me is Amazon replacing their review search box with "Rufus", which searching the entire context of an item on Amazon, including descriptions, reviews, everything. It then wants me to ask it a question instead of doing a boring search for keywords.

If I'm looking at a product and want to search the reviews for the keyword "battery life" and see what real, actual people are experiencing, I can't do that anymore. A search for "battery life" in Rufus always returns some nonsense like "Many customers report good battery life, while others say it's runtime is shorter than expected". I want human experience! I want specifics! Why is everything sanded down to "good or bad"?
