I think the main issue with Seeking alpha is that they are headquartered in Israel. You can't just issue a subpoena from a US based law enforcement agency. SA claims editorial oversight over published articles. If SA were located in the US in its current setup, they would be held accountable for publishing false or misleading articles. Hit pieces like Mako's would not be published by SA if they were a US based company. Freedom of Speech in Israel is not the same thing as here in the US.
