If you run a newly updated WordPress site then you may have gotten regular Emails saying "Some plugins were automatically updated" for your WP site. However, this can be annoying feature if you run several WP sites because you will get almost daily Emails saying each one of your WP sites has been updated. WP likely did not take into consideration that people would not want dozens of Emails each day about updates.
Not all has failed though because WP came up with a solution… manually enter PHP code Controlling Plugin and Theme auto-update email notifications and Site Health infos in WP 5.5 - Make WordPress Core to get rid of it. I was amazed about this because I'm sure the majority of WP owners do not know how to edit code they only install plugins and that's it.
Now you can see on that same 'solution' page that one person made a plugin to do it but really should you need to install a plugin just to stop Emails piling up? Your thoughts?
When you are introducing a new feature, specially one that is not critical, there should also be an option to disable it. Of course, that is extra work for the coders so they don't always want to give you an option for every feature they create but I can see how daily emails for something as mundane as to say an update was made to a plugin could be seen as serious spam abuse even if its from your own site.
