Yeap, they are just marketers, and the opportunists like we can see right now. We don't just have 20 witnesses, we have a whole list of witnesses, if/when the top ones disables their nodes, next 20 will be keep working. So please just don't get fooled by marketers whos trying to turn this chaos into an opportunity..

And afaik, disabling nodes is not just oh I'm bored I'm shutting this thing down. They needed to revert the latest changes (HF20).

It can be clearly seen who deserves a vote, who's actually solving problems.

And I couldn't find the source article but there was a consensus to revert the hardfork 20, so it took that long.

I'm not a witness nor a programmer. I just read and this is what I get so far.
