OByte use DAG as IOTA trying also to use - since years, but IOTA can't solve DAG well. IOTA seems to be the "first" and "big" DAG project, but IOTA isn't a true DLT, because the centralized structure through Coordinator. IOTA will be sold as DLT, but IOTA isn't a DLT project. So is IOTA a simple scam.
I agree that the existence of the Coordinator makes it horrible solution, but it's still a DLT.
DLT stands for distributed ledger technology, not decentralized ledger technology.
DAG is just a database structure, a graph of nodes (transactions) that should be linked so they form specific direction and not circle back to previous nodes (transactions).
Same as blockchain is just a database structure called linked list of nodes (blocks), technically it's also graph if you take account all orphaned nodes (blocks). Some say that blockchain needs to be decentralized and PoW too, but the main point that makes blockchain a blockchain is the Byzantine Fault Tolerance, which is also requirement for all DLTs. What makes the DLT a DLT is that the data is distributed and all nodes (databases) come to same conclusion (they add only valid blocks/transaction to the database in same order on all nodes even if they are received in different order). This solves the double-spend problem.
Most mainstream people now call everything a blockchain, while what they actually mean is DLT.
Both blockchain and DAG cryptocurrencies are DLTs. What DLT is not - a single database or multiple replications of a single database, which is operated by same operator.
Obyte was a DLT even when all witnesses were operated by Tony. Now with 2 witnesses replaced, Obyte is even more decentralized than how Libra was suppose to launch (15/100 validators = 15%, 2/12 witnesses = 16%), but main difference is that Obyte witnesses don't vote on valid transactions or double-spends, they just provide transaction ordering with their own transactions.
Cryptocurrency platform where the governance entity can censor transactions is still a DLT, just not very good one (Hedera Hashgraph, EOS). Bitcoin can be censored too if mining pools collude, but even then, it is still DLT. For example, mining pools could agree not to add any Satoshis transactions to new blocks and Satoshi would be fucked because there is no way he could build a mining farm that powerful now to compete with existing mining pools (unless he already controls one). It will still be blockchain and DLT, even if they do censor Satoshi.

I like the fact that very little is given for free these days.
Of course, it's a matter of taste whether you holding that copy on second drive or, say, on removable flash drive.
