Interesting feedback but I would strongly disagree with you. Although large companies are slow to adapt, or shall I say may not be the early adopters in all cases, they certainly are NOT arrogant.

If that was true then companies would not last long, the fact that there are companies that have been around for a very long time, is a testament to the fact that they are always changing. It is very rare for large companies to fail, Lehmon Brothers, Kodak are rare and are used as extreme cases in MBA's for dangers of not changing.

As much as the founders and owners of these companies may think they are above the rest, you have to remember that once listed you are now accountable to others, and if you don't you will be kicked out, look at Steve Jobs he was fired from Apple and there are many more cases of owners being fired when they don't perform.

Facebook already attempted a blockchain chat project about year ago and then gave up on it, I am sure they are looking at it again. KIK is launching one in the next few weeks.

All the big companies, from microsoft, IBM, banks etc.. are working on blockchain.

If the arrogance of the owners of the competitors is SteemITs only success factor then in my opinion the future doesn't seem bright.
