Hello there,
I wouldn’t agree with you about naming Action Scheduler as being a malware. It is widely used among a huge number of sites, and this library is embedded inside WooCommerce, WPForms, WP Mail SMTP – to name just a few of the big players. Also, it loads itself only once even when used in a lot of plugins on the same site.
The Action Scheduler library is operational and used only if you have enabled the “Usage Tracking” option in plugin settings. This option is disabled by default. If enabled – it helps our team to better understand our users and their website needs by looking at a range of variables in their plugin settings, WordPress (its version, locale, whether it’s a single install or a multisite), and web host (PHP and MySQL versions).
I hope that helps!
