Anyone can provide Postgres, MySQL or other open source databases as a service.
For this reason, there are many providers to choose from, and there is a healthy amount of innovation and competition in the space. Prices are set by market and demand, as it should be.
And then there is MongoDB where only a handful of providers could negotiate a license, and the price is set by MongoDB Inc.
In my opinion this is by no means "fine" from a user perspective as we are talking about database software.
If anyone did freeriding, it is MongoDB Inc. who chose to freeride on the open source community for marketing purposes, before switching to SSPL.
It is the opposite. Amazon would have released MongoDB as a service, same as they do for PostgreSQL or MySQL. As MongoDB changed license they implemented DocumentDB instead.
Note AWS significantly contributes to PostgreSQL and MySQL communities (though you could always want even more) but of course does not to MongoDB. While this is fine for MongoDB Inc I think it is not great for MongoDB community at large
