Large corporations, which have become governments in all but name, are the only ones with the capability to create ML models of any real value. They're the only ones with access to vast amounts of information and resources to train the models. They introduce biases into the models, whether deliberately or not, that reinforces their own agenda. This means that the models will either avoid or promote certain topics. It doesn't take a genius to imagine what will happen when the advertising industry inevitably extends its reach into AI companies, if it hasn't already.
Even open weights models which technically users can self-host are opaque blobs of data that only large companies can create, and have the same biases. Even most truly open source models are useless since no individual has access to the same large datasets that corporations use for training.
So, no, LLMs are the same as any other technology, and actually make governments and corporations even more powerful than anything that came before. The users benefit tangentially, if at all, but will mostly be exploited as usual. Though it's unsurprising that someone deeply embedded in the AI industry would claim otherwise.
