In a zero-knowledge setup, the client needs to trust that the setup is actually zero knowledge, and that future updates will not change that. Essentially the client needs to trust in the absence of incompetence or malice.
In a classic setup, the client needs to trust that the service provider is not malicious or incompetent either.
The level of trust thats required for a zero-knowledge setup is not fundamentally different from that of a classic setup. Most importantly, the amount of trust required is substantially greater than zero.
