I want to use this plugin to add Facebook Insights meta tag on my multi-site. When I network activate this plugin, it gives every single blog the option to add meta tags which is not what I want.

Is it possible to move this plugin to /network page and add one meta tage which would be added to all blogs across my network?

Yes they are.

Everyone is on wp_users.

Everyone. In the whole network.

They are not in a single table, I have more than 30000 tables in my database. Every blog has its own set of individual tables.

They are not in one single table, what command shall I use to extract all email addresses from all wp_users at once?

It does not appear on wp-admin/network users menu. I installed the plugin and then network activated it.

It only shows in users menu of every single blog.

this will only export users for a single blog, I am the administrator of a wordpress multisite, I want to export the users for all blogs on my entire network.
