Says who, you? That's nice.

>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

There's no mention of "people" or "citizen" in that text. The government *cannot prohibit speech".

Of course, there are a few exceptions to that rule, but making more should have an incredibly high bar for approval, and you want to use it for advertising?

Enact laws that protect people from malicious and over zealous tracking, which I'm sure we would both agree is a gross violation of privacy.

The "right to free speech" is more a prohibition (via the first amendment) on Congress passing laws that abridges speech, and not a granting of rights to this or that entity.

even if your proposal has merit, the most contentious type of advertising seems to be political advertising . I don't read often complaints about flower store advertisements. yet politicians are not corporations
