Of course comments are copyrighted, if they happen to contain text that is novel. As an example, in the reddit TOS, they require commenters to license their comments to reddit.

Well being novel isn't the only criteria for copyright, the work must also be "fixated", and opinions in a supermarket usually isn't (but they can be, if I film them and post on reels or something; then the video itself is copyrighted)

> Fixation

> To meet the fixation requirement, a work of authorship must be fixed in a tangible medium of expression. Protection attaches automatically to an eligible work the moment the work is fixed. A work is considered to be fixed so long as it is sufficiently permanent or stable to permit it to be perceived, reproduced, or otherwise communicated for a period of more than transitory duration.
