Who cares if they extended the time for this ICO, really? Maybe they are actually utilizing their resources towards development rather than marketing and needed a little more time to gather funds. The transparency that everyone has become so fond of is, in my opinion, is rarely provable and in most cases, it's just the dev teams telling people what they want to hear. So SOMA didn't make a big announcement, who cares?
You are right, I have also seen projects where the developers kept talking everyday, nowhere to be found after the end of the ICO.
On the other hand there have been several occasions where there has been a lack of communication from the team, especially after the end of their token sale. That silence causes a lot of uncertainty and a bad morale. As a result the price of the tokens have sunk dramatically. And we still do not know the status of their business.
You can see the effect of too little communication even in this thread. I have been quite cynical because there have been no answers to the questions raised in here. Then mere hours before the end of the sale the team pops in to say the sale is extended. I was excited about Soma because of the national interest they received, but if that behavior reflects the company as a whole they will have to impress me a lot from now on to dispel my doubts.
