The downvotes are for your assumption that (1) people don't care about addressing underlying causes of suicide, and (2) people only want to fix the problem because it is inconvenient to them, and not for the sake of the people killing themselves.

It seems that you have extrapolated both these things from the fact that someone has proposed a technical solution to suicide, which is completely illogical. There is strong evidence that removing popular, easy methods of suicide actually reduce suicide rates.
