~50% of all XMR that will ever be in existence will be minted near 1 year from now which limits large pool of xmr holders to confines of the specific monero thread(s), in a subsection of this forum, subreddits and a few guys who heard about it trollbox of obscure exchanges.
(Technically it doesn't limit holders, just potential first holders, but I know what you are saying.)
We don't know how people will find out about Monero a year from now. I suspect either Monero will have been viewed as a failure by then, or the ways people find out about it will be significantly broader than those you listed (which approximately describes the situation today, not a year from now). Even then, that that is still only 50%, leaving 50% unissued.
Imagine if that same emission curve was even steeper, and instead 50% of the supply will be released in 1 month.. how about 1 week, or 1 hour..let's be even more retarded and say 1 minute. Half of all monero ever released in 1 minute; BUT the rules were clearly defined.. the [ann] thread was created explaining everything prior to the launch. (even though it may have done a half-assed attempt at a launch before subsequently picked up and saved/taken over/relaunched/rebranded months later..which incidentally is a great cover for a little headstart)
I don't think these would be very effective launches, nor a good idea, but if clearly described up front, I can't really call it unfair.
Who is being mislead here? If you don't think issuing all the supply in the first month or first minute, then don't participate. But have you been treated unfairly? I don't think so.
