Sounds like you aren't very familiar with Bitcoin. I'm talking about Core, and Blockstream. If you were truly familiar with what's been going in with Bitcoin for the last couple of years, those names alone would be enough.
Considering they maintain the /r/Bitcoin subreddit and pay millions of dollars towards astroturfing campaigns and subversion tactics, considering how they have completely transformed the Bitcoin community into a mob with half a dozen talking points and bone to pick with every single other coin out there, I don't know how you could say I'm overestimating their influence.
I strongly suggest reading a few of the links in the first paragraph of this post[0] to get an idea of what has been going on.
