Ok, I understand that. My issue is the conflating of approval with sharing.
In this case, the problem is that people without G+ cannot voice their approval. This is obviously a deliberate ploy to coerce people into joining G+, but motives aside the issue is that Google are forcing people to share when perhaps, some only want to approve.
As people have noted, whilst the frictionless sharing is good for viral marketing, in the long term it's devastating to signal vs. noise. I left Facebook largely because my stream was full of updates from people - good friends, who I enjoy talking to - that said 'John Doe likes this: "Click like for a chance to Win!"'
