My belief is that they want to tokenize Karma and any other reward/currency will compete against their new tradable currency.
I believe they had already said years ago that the r/CC moons was a test run for something site-wide.
Personally I made $300 after moons first tanked, just from some lame comments in the subreddit that was ruined by the scheme.
I will likely use my 150k+ Karma account for profit if this happens and it won’t be for the benefit of the community like the last decade of my activity used to be.
Lemmy is now where I participate in a positive way.
