Consider also "what's the point of an uncensorable block chain if the API servers can become untrustworthy and refuse to the serve the data?"

If OpeanSea can blackhole / cancel / hide a NFT on a whim, what does that say about the viability of hosting other services that access the blockchain through similar gateways?

Additionally, if such services can preform those actions, what does that suggest about the viability of financial instruments and company governance accessed through those or similar services?

Yes, this is FUD. I believe it is quite reasonable FUD.
