, this is not a violation of trust. In fact, this solution may be closer to the solution that business needs in order to integrate 'social' into daily business processes than anything else.
See, what Google notifies you in your GMail inbox is not an email. You can't forward it. You can't do anything with it except read it (or reply on G+). It is, however, a link to the G+ notification. That's some big-time integration.
Why this seemingly non-intuitive behaviour actually solves a lot of problems
One of the biggest problems about using social data in business is that you can't legally archive content that you don't own, especially if you don't have any legally binding agreement with that user. But that user has an agreement with the platform (G+), and that platform has an agreement with you. If they edit their post, you have only access to the new version of the post, consistent with your platform agreement and consistent with their platform agreement.
One solution would be to only provide a link to the comment or post. But, that is annoying: you want to triage through the content, not have to click a link and then think, 'sigh. That click was a waste of time.' So Google went to the extra step of automatically blending in the content for you, allowing you to have the ease of use associated with automated emails, without the hassle of violating user privacy.
While the solution isn't perfect, as most users don't expect this kind of behaviour, it certainly is a step forward in making the social web and the business network come together in a frictionless environment which still manages to respect everyone's rights. Perhaps what would be a better iteration would be to keep that email, with a note 'This post has been deleted' and the content no longer present. I get a lot of those notifications, and that's fine.
