We understand this concern which is why we build the vast majority of content.

We also work with component manufacturers to help them create or translate their content to various formats. Here's an example: https://www.snapeda.com/parts/4N32-X001/Vishay/view-part/.

User-generated content is supported due to popular demand, but we deprioritize it in favor of semiconductor-generated, or SnapEDA-generated content. We also have an automated verification checker that exposes the quality of UGC on each part page.
