What this bit glosses over is the PR disaster that was Google forcing Google+ down the throats of its unwilling users. For example, for years they required Youtube users to consent to the creation of a Google+ profile in order to comment or message other users. I took that as a personal affront and not only refused to consent but installed an extension written specifically to block Google's constant, full-screen begging that blocked even passive Youtube usage.
When I pulled all my Google data with their personal download tool a few months ago, there was no section for Google+. I consider that a hard-won badge of honor.
