But Plausible doesn't send its data to US-controlled cloud infrastructure? By the looks of it, they're using a self-hosted testing environment through a CDN.
This is unique to Plausible itself and not the services they provide for their customers.
Why do you insinuate misbehavior from a competitive company when you don't have actual proof?
You have the URL of a CDN network that is hosted in the US. What you don't have is the proof of this data being stored in the US. Because it is not. Their FAQ pages clearly state that none of the data is ever stored outside of EU.
Last but not least, you entirely missed my point. Plausible is an extremely successful business, do you really believe they would risk their reputation / livelihood without understanding Schrems II or otherwise?
I honestly have nothing else to say mate. But good luck with Fathom. I am sure it will be a great success.
