The article doesn’t seem to have any consistent idea of what a map maker is, including map generators, map drawing tools, and VTT that mainly let you use maps.
And kind of odd not to mention CC3 or any of the rest of the ProFantasy suite when it comes to drawing tools.
I blame ProFantasy for that. Their software has an insanely steep learning curve and the UI is extremely unintuitive. I have been using their software for 15 years and only have a basic proficiency with it. I wouldn’t recommend it to anyone when tools like Dungeondraft and Inkarnate can have new users creating beautiful maps on day 1.
Foundry can be a very effective map decorator - as in placing of props, furniture, etc after you import a plain spartan background image. Especially if you use the Moulinette module with its access to massive catalogues and drag-and-drop.
