Someone on reddit suggested it was due to spez being petty about all the awards people were giving the protests, and even though it should seem unlikely, it makes all the sense to me.
It's a leak rather than an announcement (I saw someone mention an announcement earlier, but couldn't find it), but IMO it is made more likely by Reddit's hints in the post about getting rid of gold, and it's also similar to something that has been done in a few crypto subs for a while.
I don't have the link on hand right now but iirc someone posted here like last month regarding some internal code that was discovered basically outlining a program to pay users for how much karma they get. Kinda like being a Reddit "influencer" or some shit
