By requiring government registration my guess is the hope is both that the fraudsters will be caught or dissuaded and if they do make it past the government registration then when the real devs complain Google can say "take it up with the government. They mis-licensed. We just followed their license"
Recently I created a small homepage with different re-packaged versions of Java: https://jdk.dev
All that alternative packages are free of charge but they have extended support from a number of big companies. All these companies funded separately, there's no common place for donations or something.
That's totally ok in the world of Free Software. Pick any source code you want, repackage, rebrand it, sell it as you wish and may the Force be with you. People do it all the time.
For example, if a person were to repackage someone else's open source project with a link that says, "Donate to support the development of this software" that's still fraud (assuming they keep the donations).
Back in days I paid for CDs with only open source software because internet was too slow. CDs were definitely priced for decent profit. The beauty of opensource is that we can do this legally.
