Ever since google decided that webviews shall not have adblocking I hate it when apps use them. They sort of do on ios but not on android. After adblocking got started web ads have gotten so much worse, and I have zero tolerance for it now. Ads everywhere. Distractions. Empty spaces. Blinking. So open a link in a webview and you run a pretty serious risk I uninstall your app then and there.

The twitter and facebook webviews to open links are just plain evil.

Same reason I use firefox on android over chrome.
