If the password manager injected anything else than a "paste password" button, for example anything that is a different product by the password manager authors... yes, same thing.
DuckDuckGo has made it very clear over the last few years that they don't have multiple products—they have an all-in-one solution. You can dislike their bundling and wish you could pick and choose the component parts, but that isn't what they're offering and it's reasonable of them to view this as a tutorial instead of an ad.
