The difference is that projects like Tor were certainly
not created with any devious purpose in mind.
Arguments and use cases for anonymity are very easy to come up with.
Blockchain related projects cause damage on two fronts:
- They are commonly created with the explicit goal to scam most people while making very few people rich.
- The tech around blockchains (almost) qualifies as snakeoil. The use cases are nonexistent in the way they are portrayed. This perpetuates some pseudoscience equivalent in the realm of technology. Which is dangerous on its own. Blockchain is like Homeopathy.
No other use case has come up, and any blockchain related project has to simply lie from the get go to even justify its existence. (NFTs; "block chain in gaming" which is total bs from start to finish, portrayed as if they magically make assets appear in other games, which makes no sense whatsoever; block chains where they offer 0 advantages over databases, because a single company keeps ownership and administrative privilege; et cetera)
