@GeorgLink Thanks for opening a PR and issue! I'll have to check with the team responsible for sponsors on this one since the two programs look pretty similar to me on the surface, just with different areas of focus. Maybe the article should be listing both! 🤷 I'll let you know what the team tells me.
