You referred to video with DRM as being "encumbered", and yet this post now says such a scheme is "sensible". Way to backpedal on that vitriol
What on earth are you wittering about? DRMed video *is* encumbered. Occasionally that encumbrance is justifiable. My beef with DRM is that you don't own the things you "buy". With rentals there's no pretence that you're buying anything, hence no problem. What's your point?
And Silverlight is used for far, far more than video, just as Flash was.
*Could* be used for more, sure. *Is* used for more - no, not for anything significant.
The view of Silverlight that you present is myopic and highlights the fact that you do not understand it.
The view that you present suggests that you've sunk a fair amount of time and effort into something that was clearly a pointless, dead-end technology from the start, and you're really really REALLY pissed off about it. I might sympathize if you weren't being quite so obnoxious.
Making the browser do everything that Silverlight does increases the browser's attack surface just as much as adding the Silverlight plugin does.
I see absolutely no need to make the browser do everything that Silverlight does. I don't object to plugins in absolute terms. I object to one honking huge plugin that sets itself up as a platform-within-a-platform.
The rest of your post seems to be arguing against the voices in your head, so I'll leave it there.
