This is bad news all around. It is likely a huge percentage of searches performed by people will not enrich lives but most people will use it to mine out insights that others don't wish to be publicized.
Can you imagine people being rounded up in China over this and put into prisons over their "like".
Is it, though? The search mentions a user who liked the Falun Gong branch in [a European city - they could probably anonymise this one a bit more]. I'm guessing there are a fairly large number of people who leave China to study or work, join Facebook while abroad, then return to the PRC at some point.
