I much prefer the Silm story to the later versions found in UT. But even if you go with the UT version, all the other children of Finarfin were guiltless as well. Still, none of them were welcome to Doriath. Only Galadriel sneaked there telling half-truths.
I think Tolkien realized the implications of Galadriel's behaviour as described in the Silm and the first version in UT. He wanted to make her a saint, so he sought to remove her part in the rebellion altogether - "Teleporno" version in UT.
