Hi Dave, great work on spotting the issues with the original plugin, I was actually unable to update from within WordPress which lead me here, i had already started migrating sites to your version before all this happened. I now find myself wondering what to do as you have removed your version, I understand your reasoning why but I think now is the time everyone needs to migrate over to your plugin and for that to happen it needs to be on the repository.
For the sake of us WordPress users i hope you reinstate the plugin. For now I have just downloaded the latest version of your SEO version 3.0 from the repository (I’ts still on there: https://downloads.wordpress.org/plugin/display-widgets-seo-plus.3.0.0.zip) and will update any sites running the standard version to this. i like many other hope you carry on working on the plugin and hope to see it back on the main repository soon as there is no good alternative.
Thanks for all your hard work.
