The text of the amendment, as I'm sure you're aware, reads as follows:
> Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
I admit I fail to see how this prohibits introducing a law preventing an organisation from collecting data from individuals without them explicitly opting in to it.
The EU (you might be surprised to learn) also recognises the freedom of speech (in fact it's a universal human right, see [2] article 19). However, this does not mean GDPR is not valid law, just as I have a hard time understanding how the first amendment would prohibit privacy laws to exist.
