I'm pretty sure I've seen multiple critiques that this specific law is in fact a link tax, and doesn't care if there are previews or not.

Is that wrong?

Sure, google currently has previews, and a law could be written to target previews, but I don't think this law targets previews.

It does target previews very explicitly, but it also has a much broader condition that I imagine is there to prevent Google and others from making previews something technically not provided by them but instead created by some payload they give the users of their website.
