By now most of us have seen at least on of the sites where a domainer is selling @domain.ca email addresses.
We know this is not real and made to look like the domains are in use.
However, I just stubmled accross this....
On meet.com it looks like someone is giving away a free domain.com/whatever website address.
Again it's probably not real and to me it looks like it is built to sell the domain to google meet.
Regardless, if either is real or not one would caution anyone to run a business of any sorts on either type of service. You might want it for a small personal project but actually owning the domain you are going to run a service on is still the best idea.
