Why would they put such a message if they didn't have the GDPR in mind?
I think like many other (mainly US) sites it's partly to make a statement, and partly misguided belief that they have to put some kind of message.
In reality it would be safer to ignore GDPR if you believe it shouldn't apply to you because you're not EU based. If you're doing something specifically for EU visitors then it becomes clear you're also targeting them as visitors and then you have to comply with GDPR (this popup isn't compliant).
