Anyone with a Google Account who uses Google Maps can submit edit suggestions, but they are all reviewed before publication. You can inform them if the business doesn't exist, has a different address, new website, existing website doesn't work, new business hours; all sorts of things. Not limited to businesses: includes bus stops and train stations, historic landmarks, basically anything where you can drop a pin and see a database entry.

This is probably linked to the process for Search. It's called "crowdsourcing".

The article mentions having control of the Google Business Profile. It was sometimes called "Google My Business". You can register and verify that you're the owner, and then you'll have tools to reply to reviews and manage your own Maps entry, etc.
