Its hard to point to a specific event, but I am guessing its a combination of youtubers upset with youtubes policy moving over to LBRY. I also notice some people trying to hype LBRY by making sure their videos show up on the trending page of LBRY by using large sums of LBRY to make sure their content is discovered. Lbry is a pretty cool platform and the continued improvements that have been made to the platform over the years will speak for themselves.
