Tobe clear - to charge extortionate prices for API access in a deliberate maneuver to kill 3rd party apps and drive users towards reddit’s native app.
App devs were all willing to work with reddit if they could negotiate reasonable fees, but reddit told them to pay up or get lost.
They don’t “need” that much space. It’s ridiculous, a waste, and absolutely done to make you see a “big bag” and buy it over a competitor’s bag. It’s marketing.
