Kudos to Niccolò for openly speaking about his mistake of incorrectly stating his video was not sponsored. However I think he made a second mistake which is more serve. As a content creator he must pay more attention to what companies he's accepting sponsorship from. Given the track record of malibal, this should have been a red flag in the first place.
That comes from a position of privilege though. Getting to choose which companies sponsor you is only viable if your channel is large or you have multiple options to pick from.
