Companies don’t want to be advertising the data/system providers all over their intranet. It defeats the purpose of having a clean and functional intranet. They are beholden to their employees, not the shareholders of their systems providers. And if they’re already contracted by the company - they don’t need to spruik that to the companies employees. They’d end up looking like a NASCAR otherwise.
i specifically checked this with LVT as a hedge fund negatively suggested LVT requires having “Livetiles” in the intranet URL a few years ago. This was completely incorrect, and LVT don’t feature branding in the URL or the page itself.
