It's only strange because you interpreted "Chrome made the web so much better for everyone" as "Chrome had a webRequest API", which is probably not what the original poster meant.
uBlock Origin didn't migrate to v3 because they use the webRequest API and didn't want to switch to the less-powerful replacement, declarativeNetRequest (uBlock Origin Lite uses the new API and is available in the store).
Based on this context, it seems reasonable to assume that one of the reasons the person I replied to believes Chrome isn't making the web better any more is due to the removal of uBlock Origin. And this is due to the removal of the webRequest API.
