In this context, "Raspberry Pi" refers to a category, not a specific product. Over the years a healthy category of small, Linux-running, ARM-based SBCs has emerged. Now there are numerous entries in this category, from a $33 mini SBC to the $300 Nvidia Jetson Orin Nano, including entries from Asus and a variety of fruit-based names. Even the tiny Zero has more than a dozen alternatives.
Full credit is due to the Raspberry Pi Foundation for creating the category. But if the desire is for a base for IoT devices there are entries that are far better value and more likely sized to your needs.
