We're sorry that you feel like that.
The previous developer of the plugin, dartiss, did a fantastic job with the plugin but had advertising, sponsorship and donation requests across the README and plugin to try to compensate for development costs. We have removed all of these but, in return, have added a download bar under each video. This can be easily switched off, if required, and was clearly mentioned in the changelog and screenshots.
However, we're keen to understand what we could have done better. As a commercial venture we need to add the download bar but maybe this could have been better communicated - feel free to help with suggestions on what we should have done better.
Future plans for the plugin are only to add new features to increase downloads and users - there are no plans to add anything else promotional at all as the branding of the plugin and the download bar are all that's required.
