OK, I see — sorry! But it is confusing since your player is named “Flowplayer” and the other is not. I must assume that the others were using unlicensed Flowplayer as well.
With all due respect, the logo is what appeared on FV Flowplayer Video Player after we installed from within WordPress (see Flowplayer4.png). After removal of the plugin, the logo persists on three different video players that we have tested. The overlay links to https://flowplayer.com/hello. Blaming this on the other players seems inappropriate.
