Detterring from getting Premium is a problem, I guess, though I think the deterrent is more a case of postponing Premium rather than not getting it. - Id venture the point that a tournament such as this keeps up the action and to some extent keeps players in the game on an active level, which will in the end yield a positive effect to Premium buying. There may also be some freemiums that find themselves without a slot to play the tourney in because all their games took longer than expected and thus find themselves getting Premium to be able to continue the tourney.
Its impossible to say for sure what the end effect will be, but I think that if there is a negative effect to buying Premium its likely neglible.
As for the definition on when a freemium is freemium, its of course up to HA to determine, but the freemium medals/prizes are seemingly there for the newbees and the players that get far in the tournament in spite of the extra challenge of 4 slots. - Its not a major disadvantage, of course, but still...
As I read it, its hard to call it differently than you are a freemium player if youve been a freemium player for the entire tourney and otherwise a Premium. - Possibly excepting Premium time that the player doesnt have control over, such as referral time. But its going to be hard enough to call without exceptions
