The MoD denied Russian claims that shots were fired across Defender's bows or bombs dropped in her path, & that they chased her out of Russian territorial waters. It didn't deny that Russian warships & aircraft were hassling her. That video doesn't show or mention any bombs being dropped. Video from the Russian coastguard vessel shows her gun being fired, but apparently pointed dead ahead - while sailing on the same course, parallel to Defender. The same video shows Defender sailing serenely on an unchanging course, ignoring Russian demands that she change course.
You can claim that the MoD's statements omitted information, but nothing in that video, or Russian videos, directly contradicts them.
