Depending on how this goes, companies will need to change how they act in fear of the hammer coming down on them next.
Google commands a higher market share % of search than Microsoft does of personal computing OS.
I can choose iOS over Android. Bing over Google. Yahoo over Gmail. Dailymotion over YouTube.
Why is it a problem that google makes a superior product and people choose it ?
In all studies, when consumers get faced the decision to choose freely any search engine, most of them keep going back to google. Why is that a problem at all?
I'll be candid, it's good ... it's a hair less annoying than google, the results are just as hit or miss.
Here is the thing, if I need to BUY something Kagi falls flat on its face.
I find myself going back to google to shop, and to be candid it has drawn a contrast for me on spending. The "extra step" to buy has slowed me down.
I dont think breaking up google changes consumer behavior. It creates a hydra out of a snake.

This article states that 25% of market share may be sufficient. That is not how I learned it in my economics classes: there we said it's 60% and values below that could be oligopoly (a small number of companies holding ~90% market share).
As for why it's bad: a single provider may choose to degrade their service, or increase charges, or create an unacceptable TOS. They would likely not be able to do that if there is an acceptable alternative.
