I personally enjoy knowing that the communities I’m a part of are decentralised and don’t exist to show me ads. I also like being able to use an open source app to access them.
This is why I don’t like Reddit and wouldn’t call this a clone.
Honestly I think an emulation would be a better analogy.
They said they forgot to add the license. I think it’s best to give them the benefit of the doubt and believe it was always meant to be open source, even before being posted here.
