I think it was a good idea to add author’s/manufacturer’s name (and maybe additionally the author’s URL) to each plugin for being able to uniquely identify them.
Some plugin authors use more or less different names of their plugins on different platforms, e.g. on codecanyon, wordpress plugin repository and own website. Also on your site you sometimes use names that differ from the name the author uses on his website, and if names of different plugins are similar it is often difficult to identify it. Often i have to use the plugin version for unique identification.
Thanks in advance!
