Imagine that the damage from this law has already been done and act based on the new reality. If you cannot ensure the protection of your users' data, then teach them or give them a ready-made tool to do it themselves. And explain everywhere in your advertising why it is safe.
You don't have many options. Either go underground, like darknet sites, or make radical changes.
You wrote above that you want to join forces with other VPN providers. So join forces, but not primarily to write about how you oppose this law, but for technical and legal solutions.
Speaking of average users, I am one of them. I am not a technical specialist or a lawyer. But I will never believe in any privacy policy because it's just letters on a screen. If the special services of one of the countries come to you personally and threaten your family or torture you (of course, they never do that), then in that very second you will collect all the logs and not write about it anywhere.
That's why the average user doesn't care. They care about speed, stability, and convenience of payment and use. Moreover, all VPN providers will face this, not just you. So you are on equal terms.
I would like to say a lot more, but the hub format is not convenient for this. So I will write as you respond, if it makes sense for both of us.
And I will repeat once again that the easiest thing to do is to make the logs identical or false, but from the user's side. You can store them for 100 years, but they will be nonsense. And you will be clear before the law because it is not you who does it, but the users. And you store everything very conscientiously.
