In summary, I'd say some are either pointless and/or exploitative, e.g. because they don't understand the space or they're trying to issue securities without have to comply with IPO regulation. But some are genuinely transformative, e.g. using tokens as a mechanism to incentivise performing operations in a hugely distributed manner.

I haven't looked into them in detail, but given the relative lack of reference to them in the sector I'd imagine Kodak and Iced Tea fall into the former group. Given Atari are a long established company I wouldn't be confident about the odds of them falling into the latter either, but we shall see.

I'd definitely recommend reading https://blog.ycombinator.com/the-decentralized-future-series... for more information if you are interested.
