The SegWit2x fork that was due to go ahead on November 17th (and was cancelled on November 8th) would have increased the block size form 1MB to 2MB, and nothing else. Segwit itself is already activated.

The new 'SegWit2x' due in the next day or two is led by another team of people, and aims to deliver completely different things to the original project: it increases the block size to 4MB (not 2MB), premines 2 million coins, switches from SHA256 to X11, changes block time, changes difficulty recalculation algorithm, makes some not-clearly-defined claims about stealing Satoshi's coin, and promises some future features that will almost certainly never be delivered. The *only* thing it shares with the original project is the name.

Actually, it is just another altcoin forked from Bitcoin. By itself, that's fine: anyone is free to do that. But many people see the SegWit2x name and assume it is a retry of the last SegWit2x fork, which it isn't. The devs are claiming they are renewing the cancelled project, which they aren't. This is where the fraud is.
