The app gets access to device fingerprint, that's the main problem.
Actually i think you could still use some third party clients but you have to pay, since the app provider too has to pay api fees. But at least with the paid 3rd party apps you can avoid the fingerprinting. Although, paying for the client app also poses its own privacy problems, as well as filling the coffers of those companies, which you might not like.
So, browser then? 🫤
