The author appears to be suggesting people don't use third party services when they do development in a local environment ("Another limitation is you can’t use a closed source or 3rd party services."), which seems like a very dubious claim. I suspect there's some subtle nuance in his meaning that's not coming across in the way it's written.
Hi, the author here. This point is about the limitation of local development when you need to work with certain closed-source software that you can't install on your local machine. This can be either because the software requires special hardware, or has licencing constraints.
At that point, "local" development environment is no longer a possibility as you would need to most likely connect to an external service to be able to consume the features this close-software provides. At that point, you are no longer within your local environment but have sort of a hybrid approach.
This is where the "reinventing the wheel comes". In case you don't want this dependency and don't want to embrace a cloud-native approach you will either need to design your own custom-made solution to replace that missing service or make a certain compromise by picking an alternative one.
You might still say it sounds "dubious", but it is an opinionated view of how I see the future of web development changing. The changes might not be so obvious now, but the trends are slowly surfacing and pointing in the direction of a cloud-native future.
