> way for investors to dump a company with no real business model, yet, onto the unsuspecting public.
The "unsuspecting public" are people who bought a stock with full knowledge that they don't know what they'll end up owning. The "unsuspecting public" is a mischaracterization, people who invest in SPACs aren't doing so unknowingly.
SPACs aren't automatically part of the typical portfolio (like, say, the S&P 500). People who own SPACs went out of their way to buy them.
I completely agree with your other points, but we have to acknowledge that the victims of a poorly executed SPAC merger isn't your blue collar worker, it's people who sought out a highly speculative asset, and that's what a SPAC is.
