Orange Essence Disenchant value

As a rioter stated earlier, the disenchant value of all fragments in the new preseason will be nerfed to about 20% of what you need to unlock the shard permanently.

My question is, why is there a change to the orange essence system? I understand the merge of IP and BE will make BE nerfs and rescaling its purchasing power perfectly logical, however nerfing the amount of orange essences you get for disenchanting skins and ward skins seem to be a direct money grab

I'm sure people who are willing to monetize your game has no problem spending said money even without the incentive of getting orange essences to unlock their skin (most people just buy the skin outright), and i personally am quite offended that riot would use such an underhanded tatic to raise their stock.
