To further your Chrome analogy, this particular browser update breaks some peoples' favorite sites, rearranges the UI they've grown comfortable with (but inconsistently), displays ads next to the navigation bar, includes a built-in unique advertising id, pushes sponsored extensions on users, deliberately makes it as hard as possible to change the default search engine (and periodically reverts to the default anyway), and is the last update they can choose to decline, after which all future updates will be forced on them, closing all tabs and restarting the browser whenever it feels like it.

Oh, and also, their choice to decline this particular update is being actively subverted using dark patterns to try to trick them into upgrading.
