It's absurd to complain about this when they are one of the few institutions working on fighting aging, arguably the most important problem humanity has ever faced.
Who cares if it's capitalist-driven? It's not like governments don't, or never, had the opportunity to attempt to tackle the same problem - they simply never took it, focusing on the trivial day-to-day issues, while overwhelmed with bureaucratic tape. And it's not like nonprofits attempting to solve the same problem don't exist either (https://www.sens.org/, https://www.lifespan.io/), with limited success. A massive financial juggernaut backing this initiative is exactly what it needs.
What other solution do you propose?
