STX token has afaik notable pre-mine that went to the authors. If you check Stacks documentation then it tries really hard looking like it's build with/on-top-of Bitcoin, but in reality it's at best remotely connected with Bitcoin.
In the dApps listed there are couple that were just part of their Demo day, but don't really seem to have connection to Stacks, for example Moon. Other apps just have this feel of "we take nice looking company website template, we clone some existing idea and we add login requirement with Stacks wallet".
I'm happy to be proven wrong, but this just raises too many red flags for me.
