I've noticed it too but I don't think it's only because of the exodus.
I think it's also because by removing mod tools and opening the floodgates for bots, Reddit has enabled all kinds of vote manipulation and content manipulation by all the shill armies.
Everything from the Hasbara, the 50 centers, Putin's troll farm, Musk's troll farm, whatever Zucc runs that used to come and sealion me anytime I talked about facebook's role in genocide ... all those things have come into their full power now.
