I'd argue Sam Harris' content was mostly political masquerading as philosophy. Most of his criticisms were very concentrated toward one group, and due to that, he has put himself into a corner.

For example, when he's been asked about Israel being a 'promised land', as an atheist to agree with that and to overlook the atrocities it took/takes to achieve that, is pretty hypocritical.

You might want to check the affiliations and funding/promotional channels of all the so-called intellectual dark web.
