Why not? A country can, for the most part, set whatever level of fines they want within law. You can make an argument about the practicality of any given punishment but that's separate from the morality (which, from the tone of your comment, I assume is where you're coming from).
At the base level, I suppose my point was about morality, but my intent was about rationality. A country can write laws that it can take all the money a company earns across the entire globe, but it's not a very reasonable position, IMO.
Why is it not reasonable? Because it outweighs the harm? Because it could shut down a company? Because it’s unenforceable? Because of some “it looks silly to me” standard?
I can tell you Russia’s “fine” is not reasonable because it’s not enforceable and exists to be purely performative. It’s not the same thing as Ireland putting a fine based on global revenue but still within their power to enforce.
