I think your critique is using a major false equivalence. I don't see any suggestion in the article that keeping someone from working from home is on par with forcing them to take Adderall. Instead, both were being held up as examples when discussing the question of what changes employers ask you to make in your life to create productivity. I agree that the Adderall example was hyperbolic and the article would probably be stronger without it, but I don't think any moral equivalence was being asserted.
As to your last point, you don't get paid to be productive (necessarily). You're paid to provide work, and different jobs have different metrics for that. There are for instance substantial differences between salary, hourly wage, and commission work - someone being paid a flat fee for a project has no obligation to be efficient or productive, only to fulfill their stated terms. Diminishing efficiency in favor of happiness is a perfectly reasonable aim, particularly in certain jobs.
