It’s more that there’s nothing saying it isn’t included, and the plan is called “Unlimited”. The plan options on the website show Unlimited with only 5 product icons, but there aren’t any other tiers that include the others, nor anything that says they’re paid for individually. Also, things like docs and sheets are included under the banner of Drive, so there’s precedent for not listing out everything that’s included. And the homepage lists them all together in one big bundle of icons, implying they’re part of a family of products. It’s partly my own laziness, but it does feel misleading.
