Web apps can ask for your location or microphone the same way native apps can. Just reject it, there’s nothing that says you have to accept on either platform, so to say that’s a negative for native apps is odd.
The biggest downside of native apps is you can’t customize them with extensions or user styles like you can with websites.
It's too bad because it's not like the web is incapable of providing a beautiful ux for those products. But then so why do you think these companies employ massive teams of devs, for Android, and then again for iOS, reimplementing their functionality on every platform? All that to provide you with that sweet extra smooth native "feel", 2% nicer than the web could do? No, it's not for you...
This is key. Companies pushing apps is not for your benefit. It's so they can further monetize you right under your nose and with your full permission by accepting their EULA. This is just a furtherance of the if you don't pay for the product you are the product.
It's also worth noting that I have nothing against apps. I use them to read RSS feeds, download podcasts, etc.. Yet those are independent of any particular service and there is enough choice between apps that I can use one that respects my privacy. I am not being limited in any way. If anything, it is more empowering since the developers of a dedicated RSS feed reader is more likely to design an app that is directed towards the needs of its users. In contrast, the Reddit app is directed towards the needs of Reddit.
