Because it is cheap and Big Pharma can't make billions off of it? Thought everyone knew that. I was amazed that no one thought to ask Zuck or the Google dude how much revenue they generated from Big Pharma when questioning them about HCQ censorship the other day. The "we took it down because the FDA says it doesn't work" excuse was complete bullshit- just look how many pro medical marijuana videos/posts are on Facebook and Youtube. But no one called them on that or pointed out the huge conflict of interest arising out of the millions of $ big tech gets from big pharma and the huge profits being generated by tech firms during the lockdowns. Made me more convinced than ever that both sides of Congress have been purchased by Big Pharma.
