There is certainly an analogy here to servers that respond to HTTP ("websites") that ignore the concept of "user agent", i.e., the user chooses the client, and try to force the "www user" to choose a certain "web browser", usually one funded by advertising.
In the case of handheld computers ("smartphones") the situation is even more restrictive. The "mobile user" is forced to use both s specific operating system and a specific client in order to communicate with servers that respond to HTTP ("backends"), where the former is controlled by a company wholly or partially dependant on surveillance, data collection and the sale of online advertising services as a "business model".
