AnkiHub's modus operandi has been to take over communities or projects where free exchange happens and monetize/paywall them. If you've been a part of the /r/medicalschoolanki subreddit, you know exactly what I mean. It's been hollowed out completely.
In the post, AnkiHub mentions how Anki is "sacred" to them. Yet, they have had no qualms entrenching themselves into Anki's settings menu as the only third-party ever to do so. [1] I am sure more is to come. And the language used in their post almost never helps their case, especially in the pricing and OSS sections.
I understand why Damien felt he was being a bottleneck in Anki's development. This is similar to what was happening with Bram and Vim. Ultimately, the community forked and built Neovim. Gorhill had also similarly transferred uBlock, but then came back and built uBlock Origin. So the precedents are there for a successful community-run or leader-run spinoff.
Syncing is sure to become a paid feature, and access to shared decks too.
Creating a fork pointed to a hosted version of Sync Server [2], and an alternative hub where people can share decks other than AnkiWeb [3] is paramount. As well as saving and preserving all of the decks there, as they are sure to go behind a paywall.
I, and I am sure many other HNers, would be willing to support that with our time and financially.

A really disappointing development all around & I hope it galvanizes the community to fully disassociate itself from AnkiHub & dae.
