Thanks but this is only one study and they even conclude that some non-genetic factors may also contribute to causing autism
There are many causes of autism. Research suggests that autism spectrum disorder (ASD) develops from a combination of:
Genetic influences and
Environmental influences, including social determinants
My link isn't a study it's a layman's terms explanation, but there are lots of studies. Your link mentions a meta analysis of 7 studies concluding that up to 90% is genetic.
Yes environmental factors are there too, otherwise it would be 100%, but there's enough evidence pointing to genetics that it is really disappointing when people try to find spurious links to false causes instead.

What heritability actually means https://dynomight.substack.com/p/heritable
> I couldn’t help but notice that there’s near-universal confusion about what “heritable” means. Partly, that’s because it’s a subtle concept. But it also seems relevant that almost all explanations of heritability are very, very confusing.
For example, they say speaking Turkish isn’t heritable but speaking English is. Weird!
> Heritability can be high even when genes have no direct causal effect. It can be low even when there is a strong direct effect. It changes when the environment changes. It even changes based on how you group people together. It can be larger than 100% or even undefined.
Autism speaks is a spiritually evil organization and the fact that you unironically linked them implies that you wish to wage cognitive warfare against all autistic people. Autistic people will respond by making sure you reincarnate as a durian fruit.
