Is SponsorBlock - Skip Sponsorships on YouTube safe?
SponsorBlock sends watched YouTube video IDs and skipped segment IDs to its server for skip-count telemetry.
SponsorBlock has skip-count tracking enabled by default, including in private windows. When it skips a submitted segment on a YouTube video, it sends the current video ID and the skipped segment UUID to the SponsorBlock server.
