The title of the article literally says "where possible". You found a case when it's not possible, and decided to argue against that... No, not all services come connected with a database. Alternatively, often times a database is an artifact of tenancy and the need to manage users which would not be needed, had the functionality be exposed as a library. More importantly, whether users realize this or not, a library is more beneficial for them than a service in majority of cases. Much in the same way how it's almost always better to own something than to rent it. Just to give some examples of the above: all the Internet of crap stuff, all sorts of "smart" home nonsense which requires that you subscribe to a service, install an app on your phone and send all your private data unsupervised to some shady Joe Shmo who you know nothing about. To be more specific, take something like Google Nest thermostat. There's no reason this contraption should ever go on the Internet, nor should it require to know your street address, nor your email etc. In fact, the utility it brings is very marginal (saves you few steps you'd have to make to reach for the boiler's controls to program it). It absolutely could've been designed in such a way that it doesn't connect to the Internet, or, at least, to never leave the local area network, and yet it's a cloud service...
