The quoted bit was about a built-in ad blocker specifically. I think the real major point is:
“There are a couple components I want to touch on here - As mentioned elsewhere, we're still evaluating the adblock Manifest V3 changes, so we're not quite ready to commit to a statement one way or another on that issue.”
And:
“Second, we're committed to a strong extension ecosystem, including ad blocking. We're still evaluating some of the latest changes here in Chromium, but we're committed to the customer scenario as a principle. To be clear, we will not artificially restrict ad blocking for business reasons related to advertising.”
That's mostly fluff. Google also says they're not restricting ad blocking for business reasons, but for performance, and they haven't banned all ad-blocking, just forced addons to use their new mechanism, so they can still claim to support an ecosystem that includes ad-blocking.
