Good Q. People can choose to build closed source tools, distribute them organically and incrementally improve. Perhaps a better way to frame it would be to have a word that summarizes the following: fiat VC funded obscure growth demons from hell that scrape everyone's personal data to sell to the highest bidder and create honeypots for hackers and governments while actively trying to lobby said governments to crush their competition and create monopolies for them, which compromises their integrity and ensures they become more powerful, hellish and evil. I guess it's easier to say closed source. Open source helps prevent the evil loop from occuring.

Of course it's overly reductive. This is a short note, not a book. The point is that closed for-profit entities eventually die. Open protocols have the chance of immortality.
