Usually it's even dumber than that. Shows use the logos to try to blackmail large companies into paying them for "advertising", and if the companies don't pay up they censor the logos.

yea all logos and names of brands are heavily trademarked, using them in your own works isn't allowed unless you get written premission/contract for advertising for them or if it's incidental use (imagine the main character running through a busy street and a small Apple ad flashes at the edge of the screen somewhere for 2s, if someone tries to sue for that courts are most likely to dismiss the case with a legalese equivalent of "bruh chill")
