We don’t know the custom of freeing house-elves. Master has given Dobby a degree Dobby is free class of 2020 shirt Perhaps the family always makes sure that the elf is given a nice set of clothes so that they’re not walking around naked, as the towels, pillowcases, sheets, etc. belong to the house. Dobby took the sock. It may very well have been a loophole to have been given a sock that didn’t even belong to the Malfoys, but it was enough to break the enchantment/custom that kept Dobby bond to the Malfoys. Both Dobby and Winky seemed to have had the choice of wearing the Hogwart’s towels. Sadly, Winky was pretty far gone in her grief to take care of herself, let along with hold down a job, but Dobby was proud of his paid employment and dressed accordingly.

The plot of the fourth book was long and complicated and needed to be significantly edited to be adapted into a movie. Most of his role in the fourth book was centered around his relationship with Winky, who never appeared in the films. Neville being the one to tell Harry about Gillyweed helped streamline the plot and gave an extra clue to “Moody” being the one behind the plot to get Harry to the graveyard. I imagine it’s also much less expensive to have an actor appear in a brief scene than to CGI Dobby. She had sold the rights to her books to be made into films, her approval for anything else was simply done out of courtesy, but has no real powers.
