Yes, but this doesn't do absolutely anything to prevent this.

I've helped elderly family members and non-techie ones who barely know how to open a facebook account - none of them had "malware apps" installed. Their problems were mostly these:

- Websites asking for notification permission just to spam with unrelated malware or porn notifications

- Their calendars being filled with events that are nothing but links to porn or gambling sites, leading to constant notifications

- Apps that don't work yet are filled with ads - blood pressure meter on your phone, sugar level measurements, step trackers - filled with ads and trying to get 1000$ purchases

- An app actually being a launcher filling your screen with ads.

- Hell, even I, as someone who has deep intimate knowledge of Google Play Billing, got scammed by an app when upgrading from their weekly to their monthly offer, with them now charging both.

Google can intervene at any point here, they have reviewers, they control the store, they control the browser, hell, they basically control the device. And they have rules and policies for it, but it's convenient for them to ignore it. They have their cash cows and will fight tooth and nail to protect them as long as it makes them profit.
