All of these technically could have zero day vulnerabilities and people/companies who made it don't have the resources to buy 20000$ of tokens to go debug them... Maybe they don't care but if they do, what if they can't afford such models or get access in time.
I would like to know how can someone like me defend against them?
$20,000 - how many developers do these hardware companies have that they need to spend that much? Claude Team Premium is US$125/mo for a seat and even cheaper if you buy annually...
