Hextech crafting concern

With the recent changes to Orange Essence values, Riot has been defending themselves by saying that they:

1. Are losing too much money through the hextech system
2. Plan events to give us "more free stuff" - TLDR that is a lie so far because the event is the same as always just the rewards are worth less
3. Added "bad luck protection" and "extra goodies" to the lootboxes - noone should consider adding RNG on top of RNG a justifiable return in value (regarding the RP to Lootbox value drop) That being said, I haven't seen anyone else think of this and I wonder: Is there any kind of statistics that would tell us how many FREE hextech keys and chests have been used compared to PURCHASED keys and chests? And if the purchased ones numbers would be larger, would Riot really lose that much through this system?
