I'm curious about how you're establishing that the people objecting to this are the same people who were early adopters of Google search.

I was an early adopter of Google search back in the late 90s but I'm not that bothered about what they're doing with plus (I'd rather they were handling it differently but I'll take it or leave it).

I do see that some of the people who are objecting are potentially significant voices - I tried to reflect this in my post by saying they were people who had thought this through - but sadly having a good point doesn't mean that you'll always win the argument, particularly where massive commercial concerns are involved.
