"Where did ideas have had a better chance..the X as it was or the X as it is?"
It depends on which perspective you use to view it doesn't it?
You called the previous version, and to paraphrase, some woke leftie Twitter internet forum, so one would assume and in fact we know that the ideas that suit that narrative would be promoted over others. In this case the other is you and you hated that.
The current version of Twitter, X, is owned by Musk. His current mission is to run the platform as anti woke anti leftie, so he promotes that narrative over others. In this case the others are the woke leftie brigade. Which you love. So you see it as a better place to be.
It's confirmation bias.
It's so simple, for someone such as yourself to by unaware of how this works, really is astounding.
