Essentially, they get to pass off an email advertising Google Drive/Google One/who cares as an emergency transactional email, pretending that I'm close to running out of space. Can't block it or I'd be blocking everything from Google. I can try to filter it but they keep changing the wording. Evil and intentional.
I wonder if the regulators can be asked to extend the "Do Not Call" registry to include barring such app notifications? For example, the National Do Not Call Registry in my country has now been renamed to National Customer Preference Register (NCPR). This now gives indians more fine-grained options to choose what kind of marketing calls we want to bar or receive:
> “Transactional message” means a message triggered by a transaction performed by the subscriber, who is also the sender’s customer, provided such a message is sent within 30 minutes of the transaction being performed and is directly related to it. Provided that the transaction may be a banking transaction, delivery of OTP, purchase of goods or services, etc. ... “Unsolicited commercial communication or UCC” means any commercial communication that is neither as per the consent nor as per registered preference(s) of recipient, but shall not include: (i)Any transactional message or transactional voice call ...

They can extend this to mobile OS notifications and ask Google, Apple, Samsung etc. (mobile OS makers) to ensure that all promotional messages through such notifications are blocked, and only "transactional messages" are allowed.
