Imagine Ladybird is developed and is successful. Lots of people use it to read websites.

But then Badcorp takes the code and builds their own varient with extensions. Badcorp is big and has lots of market share. Lots of people use Badcorps's browser, and because lots of people are using it, lots of web developers code for it, including coding for its extensions.

Soon, lots of websites -- including Badcorp's own websites, and they have lots of popular ones -- use the extensions in the Badcorp browser.
