I mean, that's not really how "opt-in" works for features that your company owns; you might have to "opt-in" technically but your company will probably make that a little more mandatory.

I do agree that the blog post, headline, and HN comments are as usual quite an overreaction, but this feature is pretty gross. It's also weird because the controversy/grossness-to-utility ratio seems awful, which either means that Microsoft product management has gotten as bad as everyone thinks it has or there's some future plan to make it more "robust."
