In reply to Miroslav Glavić.

You may not realize it but a simple google search can turn up a list of most of the plugins on your site. I can literally find nearly all sites that run my Popup Maker plugin by searching for the js file that gets loaded. This can't be said about all plugins, for instance a plugin that doesn't leave a noticeable trace on the front end.

That said the information is scrubbed from my knowledge and is purely used for statistical analysis. This is also how they make decisions such as when to drop support for older versions of PHP & MySQL. They have to know this information or they may make bad decisions which could break millions of websites.
