What Companies Are Doing This?

i remember some talking to of these companies, and they would talk about network effects. And we would sit of sit and think, am i really going to give all my friends a soft ware key to my house? It's not that i don't trust you, but like, why would i give you lik you you wouldn't want a key to my home?" That brings to an interesting point of what we were talking about y which is, this is not all technology.
