I think it is immaturity of Ke, want something, but too inexperienced to pull it off.

Red flags been:

1 - China
2 - EOS (in that case EOS not to blame though :-)
3 - Unrealistic model behind (fairness and only positive stuff...)
4 - No strategy
5 - Only mobile
6 - no USP
7 - Poor tech

Some of your listed red flags may indeed be red flags, but others are not imho, but simple opportunistic and idealistic (2,3) and product choice (5). If no Strategy (why announce it? no startup became big informing the market about strategy from day one) and no USP (I think the whitepaper had some USPs, but the execution is not according to whitepaper which is a big shame) is a red flag, I'm afraid this is the same for Steem from day one.

wrt Mobile only, please keep in mind way more people have mobile phones in the world, then laptops and desktops. Also, with a laptop/desktop UI, one can more easily create long copy/paste posts that will be regarded by the community as genuine. Everything has its upside and downsides; Fact of life :)
