ITC is not a copy of IOTA.
ITC will use its own Blockchain, not the Tangle. Furthermore, ITC and IOTA have completely different aims. While IOTA seeks to facilitate microtransactions within the Internet of Things, ITC is geared towards improving security within the Internet of Things. Rather than being a copy of IOTA, or even a competitor of IOTA, ITC can work alongside IOTA.
I don't think they're slow with their updates...they posted one like yesterday lol. https://medium.com/@IoT_Chain/itc-project-progress-update-2018-1-6-2018-1-12-dbb8d6e0db49
Overall a very good project that deserves the attention. I'm sure that will be the case in the upcoming weeks.
