TFA literally says don't use full screen modals, ever. I disagreed with examples of that not being necessarily relevant with the way today's applications can work.

Important from the NNGroup article you linked even demonstrates great modal usage and states "3. Modal dialogs can be used to fragment a complex workflow into simpler steps." and "4. Use modal dialogs to ask for information that, when provided, could significantly lessen users’ work or effort."

That's important - modals are not just intrusive pop-ups as many designers and others in this thread have decided that they are. Again, every element can be used inappropriately but that doesn't mean the elements are to blame.

You're right about full screen modals, I've seen those done right and "never use x" is rarely right all of the time. And modals can be done well, but 90+% of the time I encounter them, they're not. They're not related to the workflow I'm currently engaged in, they don't save me any time, they don't serve me.

Again, I'm not saying (and I wouldn't characterize TFA as saying) modals per se are bad. But the priors are such that absent any other information, modals are suspect.
