I am not sure if USCIS officer deliberately pushed my case behind when I made an inquiry - well I am not trying to blame anyone but why are the cases from about 5 people pending and all (almost all) cases before and after that group is approved so early. Sorry, that I am trying to build my theories here but that seems to be the one way to think about my problem and pacify myself.
With the recent immigration trends building up, I now think that this new administration is going to interpret the benefits provided under TPS in a very different light. See the news that there is an effort to discredit the legality/credibility of the people who used food stamps, obamacare https://www.washingtonpost.com/blogs/plum-line/wp/2018/08/07/trump-and-stephen-miller-are-now-targeting-legal-immigrants-and-it-will-get-uglier/?noredirect=on&utm_term=.33c5abe0c4e9
It won't be a surprise to see that there will be an effort down the road to demonize/devalue the TPS beneficiaries - which might make @pyacman right in retrospect if it ever happens.
