That’s not true at all. It really depends on environment and proper curing. Where I live, carpenters will rarely use dimensional lumber that’s been stored indoors for these very reasons. It’s stored sheltered outdoors, where the air is dry but temperatures can fluctuate between +30C and -30C depending on season. When it’s been through that, it doesn’t automatically screw up like a silly straw the moment you bring it indoors into a warm and more humid environment.
