> Neutral means staying out of it.
What do you mean by staying out of it? As far as I can tell, you can't stay out of choosing which data you use.
By staying neutral, it seems to me more that you're arguing for putting blinders on.
In terms of tech companies making choices, you seem to be arguing that they shouldn't intentionally curate their datasets. I would argue that intentional curation is their job, and should be done thoughtfully.
Larger problems could happen if only one (or two) companies end up effectively controlling the technology, as had happened with internet search, however, that is a completely different problem. It's one of lack of diversity of people making choices, as opposed to a problem caused by people actually making those choices.
In other words, I think we should hope for many different large models and datasets, so that no particular one stifles the rest. I think this is the larger point you were trying to make, though I also think the focus on ideology is a tangent from this.
Personally, I'm of the opinion that people should intentionally, carefully, and openly act with their biases (sometimes called ideology), instead of attempting to hide them, ignore them, or somehow "remove" them. Whether or not they do, however, is a different point than whether or not things end up stifled inside walled gardens.
