This point is being made each year again and again, that it is getting more and more political. I also had that impression myself.

However, I was surprised to see some actual statistics that it was already political right from the beginning (sorry, no ref, I barely remember).

And there are always also a lot of technical talks. It is not really phased out. Maybe just some of the political talks get more attention. Or the attention to political content increases. Or maybe my own attention to political topics, and I just ignored that earlier. But when you look for technical content (at least on a regular C3), there is plenty.
