situations vary. typically, I'd say never use a pad.
But what about rescue pups that are 3 or 4 weeks old and having issues, including severe weather I wouldn't force a 4 week old out into.
Or a sick puppy/dog?
Or a dog like Cara who originally cried and shook with terror if it was raining. Add the winds (Common in GA and Israel) that so scared her she would pee on herself as she looked out the windows and the view confirmed her worse fears.
Cara goes out in the rain most of the time. She seems braced, hates it, but goes. But storms? When I have a big potty pad on the enclosed porch? Sorry, there are "not an option rules". But there are also compromise ones. I'd rater have my battles elsewhere. When I can carry it with me and not have her fixating on windows as it rains.
Choose your battles. If this is one for you,go for it. If it isn't, consider that sometimes people have different needs.
