I don't know if we can call this platform equal of opportunity. The idea, the inception is here but we are not there yet. A lot of power is still in the hands of a few and need to spread around, everything is in English which can hold back a lot of people wanting to post in a foreign language or aren't part of one of the massively spoken languages. The filters to get the content you're interested in are rather unefficient for now and a lot of people are here for pump'n'dump. Sooo, I think Steemit will do a lot better in a bit and needs some maturation of course, there is no shame in that. But it's probably a bit early to talk about equality of opportunity even if used properly :)
