Musk and Twitter support said it was intentional, you only get 60 free tweets a month on a bot account and then have to pay for Blue, which the iembot guy obvious can't afford and he won't give an exception to the NWS.
I don't know how anyone who's even slightly interested in the weather can defend Musk's changes, he completely broke many warning and spotting dissemination APIs and resulted in the banning of 16 IEMbot accounts for "spam"
