I feel those comments are a bit tough on them.

From their recent videos, you can still tell they know what they are talking about. Yes, they are less serious compared to hand only videos but they are far from lazy I would say (you can tell there are still some thought put into the scripts).

Also, they are producing more videos. I think they are just trying out different styles of content creation. I relish that they seem to enjoy the process of making such videos with casual banter and jokes. We should support channels for being creative and willing to go out of their comfort zone.
