Earlier quoted context omitted.
Free speech means arguing against messages one disagrees with, or ignoring them, but not trying to suppress them. No. Free speech refers to protection from the government censoring or jailing for speech they don't want said. If you're relying on a private company, especially one who retains the rights to take down your video at any time for any reason, to disseminate your speech and you're worried about them doing so…
The US Supreme Court has a different opinion. They have ruled that private areas acting as public forums are still subject to the first amendment. See Pruneyard Shopping Center v. Robins [1] > A state can prohibit the private owner of a shopping center from using state trespass law to exclude peaceful expressive activity in the open areas of the shopping center.

No, they've ruled the opposite, as your own source explicitly states. Pruneyard permitted California to impose free speech obligations on property owners via the State Constitution that the Supreme Court had previously found were not required under the First Amendment. (In effect, it found that the federal First Amendment rights of the property owner did not extend to blocking the state action.)
