Why not? So that tech companies can collect more data? Because I don't see any reason why browser solutions aren't viable in the age of overpowered smartphones and 5g networks.
What does this law actually look like? What's the legislation? "You're not allowed to link to a native app from a website"? Are you saying iOS universal links - twitter.com links opening in the twitter app - should be illegal?
I don't understand how you can legislate against this without also banning a bunch of legitimate use cases.
We did it with browsers, didn't we? And we rightfully complain when MS is defaulting back to Edge after an update. Sure, LinkedIn, ask me once if I want ro use the app. Accept that I stick to the browser / website and don't make the website experience arbitarily worse on mobile just to nudge me into using your app. Same principle, and honestly a lilegit use case for cookies so that LinkedIn can remember my decision.
I gave you a reason why I think this pattern should be illegal under, e.g., the EU privacy laws. So what's your reason for believing it should be legal to force people to use an app tgat collects all kinda of tracking data about users over an equally fine browser solution?
For the longest time the web client was super glitchy (stuttering) on MacOS. Haven't used Zoom for maybe 2 years now though so things might've changed.
