Both Steve and Elon made stubborn decisions, some of which benefited and some of which hindered their companies' products.

I kinda agree with steve jobs on both of those calls. if your "mobile app" is just a wrapper around a web page, I'd rather just have a bookmark shortcut on my homescreen. what's the value add?

I don't think either of those is very similar to the wiper thing. one is using the leverage of owning a major OS to force third parties to do something better for the end user in a context where the stakes are pretty low (ie, no one is going to die). even if it works out in the long run, the wiper only benefits tesla. and in the meantime it is a serious safety risk for the end user.
