Heh on my HN client for Android (Material) I never could open TechCrunch articles with the built-in browser. I gave up on using the built-in browser as a result. I wouldnt outright ban TechCrunch but I agree it can be entirelt unusable.
Sidenote: Wondering if anybody outside of Google offers an embedded browser component for Android like Mozilla and co. They might be able to provide a better experience.
