That sounds about right. Reddit just isn’t a fun place to be, and hasn’t been for years. I’m not sure what the value proposition is for Reddit anymore, other than for the owners of Reddit.
Just because it isn't fun for you doesn't mean it isn't fun for others. Fun, humour, and social interactions in general are very subjective. There's clearly people that do enjoy that kind of humour or else Reddit wouldn't be where it is today considering it's basically always been like what you described.
