I still struggle to see the harm, or what a remedy would aim to fix. Of all the possible antitrust fights to pick (Comcast, Apple, Meta, etc.), I'm not sure this would even make my top 10.

Google search is still the best out there. If you want to use a another web search, the switching cost is lower than almost any other product/service (e.g. compared to OS, cell phone network, ISP, etc.). Competitors like Microsoft, Apple, and Meta have ungodly amounts of money, but have barely tried in web search.

Despite Google being a more open and better web citizen than most other players, they have still been hit with actions on the Google Play Store and search. It's hard to make sense of.
