The perception on the left is that once again, corporations are foisting products on us that nobody wants, with no concern for safety, privacy, or respect for creators.
For better or worse, the age of garage-tech is mostly dead and Tech has become synonymous with corporatism. This is especially true with GenAI, where the resources to construct a frontier model (or anything remotely close to it) are far outside what a hacker can afford.
That framing may be true within tech circles, not the broader political divide. "Hackers" aren't collectively discounting and ignoring AI tools regardless of their enthusiasm for open-source.
Safety-ism is also most popular among those see useful potential in AI, and a generous enough timeline for AGI.
