Any time there is something new everyone will sign up to try it out. Give it time. Once there are enough intrusive ads, or subtle ads shimmed into answers, social manipulation and political bias once it hits critical mass, rewriting of history, squeezed rate limits, more cost for less rate limits that number will drop if they are honest and/or deleting inactive accounts. The negative features will not creep in until they believe they have achieved critical corporate capture and dependency.
