Scope review: Pinned project README expressly licenses LibreTube for use, study, sharing and modification under GPL version 3 or later and separately identifies this exact default-app-icon path and its designer XelXen. The selected image is an original app resource, rather than promotional screenshots or third-party video thumbnails. The checked root license and README contain no exclusion of this default icon. Other differently credited icon variants and video imagery are not included.
No affiliation or endorsement is claimed; project names and marks identify their actual software. This copies an individual unchanged GPL project artwork resource, not any paid service or third-party content.
