The fight is on the reputational level to prevent the critical mass of users from switching to the open platform.
So it's rumor and slander as the tools of the day. E.g. "Bitcoin is for drug dealers."
Because from the user-perspective, you are right. There is no reason to stay in the closed systems when there is an open alternative that is superior in pretty much every way - except for the lack of network effect.
In our own case here on STEEM, the value for a user to switch from twitter/fb/etc with their millions and billions of active users to STEEM with its 20-50k active users is low. So we are in the baby stages of network effect where we pretty much only have people who are looking at the larger, long-term picture as users.
Open platform enables permissionless innovation and Steem ecosystem has grown immensely in just 2 years:
And much of this development is done as open source software that allows others to build on top of it, network their ideas and gain momentum. At first glance, it may seem like a long way to go before an open platform compares to existing giants, but this growth is exponential and once the open platform starts to catch up, the next moment it is 10 times better and offers something completely different and unique to users. The adoption will happen.
Oh, definitely. It will happen. The question is when will then be now?
