See, that's how the snowball of false info turns into an BS avalanche. Polygon's reviewer was the one that brought "there is a grind to reach the true ending, the lootboxes speed it up" and some trigger happy youtubers turned it into "true ending is locked behind the lootboxes", which is wrong.
What you just wrote is one step further, calling lootboxes "microtransactions", when the currency (gold) is actually easy to obtain in game with story missions, vengeances and daily quests.
