Users who use F-Droid are already not as lay. If you distribute stuff that Play Store would ban, your users are likely not as lay, too.
Yes, it's inconvenient, but I see it as a good-faith attempt to limit exposure of lay users to scams, not some power grab.
Automated bans can be an issue, but that's an edge case. Google already had the functionality to 'revoke' an app if ordered to do so by a legal authority.
It is much more important to make a real world attack - something that is draining wallets of ordinary people across Thailand/Brazil/SEA in general - harder to achieve. One thing is a political goal of some people in the west, the other is an ordinary person not having the money to feed themselves because a scammer stole it all.
Google doesn't have the ability to change the way banking apps work with regards to transferring money from one account to another in Malaysia/Brazil/Thailand. That would be a matter for the national Governments. This is the best approach available.
