Every of the lightning talks itself had about 20 short different topics, And as I wrote these were examples, you didn't expect someone to re-enumerate them here all to refute your statement. You can easily find them yourself. Have look at this page, where others listed their favorites, there are many more. But I don't think from your reply you didn't look at the list of sessions yourself.

As someone who has been following the congress for twenty years (and if I couldn't be there, I watched streams and recordings), I have to say once again that it used to be better. The selection of topics was broader and more interesting. About fifteen years ago, politics entered the picture, and over the years it has become more and more prevalent. Strange people began to appear, and about ten years ago, this event ceased to be a cozy meeting place for hackers and geeks. I am very sad about that.

Sorry but it doesn't look like you followed it at all. We had nearly a decade of political activism surrounding WikiLeaks 15 years ago...
