Slight tangent but that's a cool looking website. Gives off a mid 00's private tracker vibe. Loads pretty fast too.
Read the report and see if the findings are super basic or super advanced. If you can't tell, then this audit report is not of value to you, similar to how my mom has no use for open source software yet I would still say it's valuable to have open source software in the world.
Because they have an excellent reputation and do good work.
