Maybe dial it back a bit? You can be firm in your opinions and have more success in convincing others if you avoid vaguely worded accusations and the like.
I don't think a conspiracy is necessary here. Three factors are at play:
1) It needs research. That takes a long time. 2) If its successful and good, the effects need to be studied in patients for years to understand the long term impact 3) Capitalism is going to try and optimize for profit, not for welfare. Which is the point you are making, except... it's not conspiratorial. Capital absolutely is out in the open about this.
It won't help the underlying AD pathology, but it's a workaround to mitigate some of the harm. It should in principle work better if done early before large deposits form in the brain.
> Capitalism is going to try and optimize for profit
This in no way allows spreading falsities and FUD about competitive prospects. It is not excusable.
Literally in the article which you clearly only skimmed and did not READ "Hong is now running his own trial in South Korea and says that he is finding the same spectacular gains in some individuals, although not in everyone."
That's very much mixed results.
