Sometimes that's also by design and can also signal that you're not the customer. For example, CIOs may hear of a product and are very willing to get on a call to learn more about a product rather than necessarily reading a landing page at all. This provides the opportunity for the company to teach a potential customer about how exactly it fits their specific use case rather than a more generic landing page (and some companies do have a solutions page with more pages for various specific industries precisely to combat this too), and also, well, to make the buyer interested enough to buy. People who want to learn more by themselves on the landing page are typically not buyers because CIO and VP level executives do absolutely want to learn even the basics from a human and be able to ask specific questions relating to their use case.
If you are in enterprise companies and see these discussions, you can see that the shift from product-led to sales-led (ie, enterprise) is a pretty conscious decision that companies make, as they know exactly the type of persona they are trying to target.
