Always a bit scary when an open source project changes stewardship like this, but I'm quite relieved to see all involved parties seem to be aware of the dangers and very much on the same page about not screwing this up.

Done right, commercial interests can often have a very positive symbiotic relationship with open source. Almost all the largest and best open source projects out there have substantial involvement from commercial interests.

I do think though that from a structural/governance perspective it's not a good idea for Anki to be owned by AnkiHub. Anki is a community project, not a corporate product, and while it sounds like the license will continue to reflect that, I personally think it would be best if the corporate structure did too. If Anki were spun out as an independent foundation (like Blender, Linux, etc) receiving most of its support and development work from AnkiHub, rather than owned outright, I think that would allow a much more robust governance structure than just having everything be under AnkiHub's direct control with some pinky promises about listening to the community.
