Massive decrease on user's activity or it's just paranoia?

Hi everyone! This time there's no heteronym speaking!

I have been checking some new dApps and of course I always check the Steem ones. However it seems that things aren't going as good as they should for Steem, or I'm just a newbie here and I would love you to prove me that I'm wrong.

I'm on Steem since November, and I'm fascinated about it! Until mid December it seemed that the user activity was always oscillating, but this last month, State of dApps is showing something strange going on:

As you can you see from the print above, there's this massive decrease in user's activity in the last days in all Steem´s dApps! As an equal massive noob, I'm not able to explain you the reason why, but I'm genuinely open to hear your explanations below.

That's it for today! Until next time! Cheers!
