What proportion of websites do they need to gatekeep before the label applies?

No, this is more like Honda putting a portal in front of the main door of the VW dealership that transports people into their showroom instead.

Just my non-scientific observations here, but it seems to me that most of the autistic people I've met tend to subtly call out people's bullshit more than the average person.

It seems like some powerful contemporary political entities are highly averse to being called out, especially if it's a subtle jab that goes under their radar.

That sounds a lot like what data scientists have to do at any publicly traded company.

This is why one-size-fits-all doesn't work if a company legitimately cares about productivity.
