How can I understand the authenticity of the platform's website?

Sometimes it feels like platform sites for game projects are created primarily for the company's image and market presence, rather than to actually explain how their solutions work. The texts are dry, the blocks are short, there are almost no diagrams, and there are no interactive elements. How do you know that the information on the site is reliable and allows you to really evaluate the architecture of the platform, the functionality of the modules and integration capabilities?
