They actually are opening up to unaccredited investors, you just need to have a CFP or CPA or something like that (not sure of the actual requirements, I just know that they recently changed them)
The change is that having one of those certs now makes you an accredited investor.
You don't have to be accredited to invest in something like a VC fund anymore using something like Wefunder. However it's extremely risky and generally painful to even find out if the thing you invested in 3 years ago even still exists.
