Computing history is rife with examples of API designers who get attacked for building walled gardens and denying user power when they ask such questions. There was a time, for example, when "data portability" was widely understood to mean that Facebook should let Google programmatically extract your data and forward it to fourth parties (https://techcrunch.com/2008/05/15/he-said-she-said-in-google...).

Today we know that there's no genuine question of user control here, because virtually every user has a mental model that a "webpage" is something different and much more scope-limited than a "program". I don't expect that steampowered.com should be able to launch the game I just bought, even though that capability is easily available from a similar-looking interface by the same developers I have installed on my computer. In 1995 it wasn't so obvious that people in 2025 would think this way.
