The myth that's being debunked here is that "WebView's suck" not that a WebView experience matches a native one. Clearly, Dan--who is an Android developer--understands that trade off given this pull quote from the article:

> Webviews give us the flexibility and freedom to choose what screens to level up as native views, instead of being forced to make everything native.

For the umpteenth time, the Basecamp team has leveraged their resources and skills to ship an entire product at a remarkable pace. Had they embraced the myth that "WebViews suck" and anything but native is acceptable, they would have taken twice the time to ship.
