I will have to disagree with one of the comments. The landing page does indeed look similar, however that doesn't stop many companies in reusing bootstrap, material ui typical interfaces, color schemes and the layout as it used as a standard.
The major thing is that functionality is different, the star background and the use of to what I call material UI cards is absolutely fine and acceptable. Nearly every 2nd crypto project use 'connected nodes' background - try blame them for that:)
Finally, the author did it as a side project for learning and it seems to be totally free.
And yeah - Good artists copy. great artists steal
I haven't done any trades based on their calls so far, but as far as I've checked most of them would be profitable (can't really say which ones would make a loss). Overall knowledge in the community is good and it's also easy to find good new projects that are popping up and missed by majority of the crypto community.
