@andrarchy explains thing well, however, Steem does not have 1 million users - not even close.
Yes there are over 1 million accounts, but that is the only figure that comes anywhere close. Every other statistic - unique weekly/monthly/yearly posters/voters, accounts holding more than 0 SP, etc point to a much smaller community.
If you then took any time to remove bots/community accounts/test and alt accounts, this figure would reduce even further.
I feel it is detrimental to continue inflating the user-base number.
Overall though , the differences between Steem and what FB have proposed are clearly stated. Cheers.
