I do wonder if it’s entirely disabled or just on the default web interface. The Mlem app still gives me the option to downvote things.
I don’t even necessarily disagree with the sentiment of not having downvotes on a platform, but it seems weird to give that up as one server on a federated network, considering anyone from other instances could presumably still downvote posts on here.
If you don’t have the time/interest in setting up NextCloud, CryptPad replicates a lot of the functionality of Google Docs/Drive, though to get more 1GB of storage you will have to subscribe.
