What's so bad about charging for a service or for tools? Just because some of the MegaCorps offer Javascript frameworks + tools for free, why shouldn't a small competitor be charging a bit of money for work that is built on top of the free framework to keep it financially sustainable? It's an optional purchase for people who might want to rather save time, e.g. when you're a small dev team trying to build something, you need to calculate the opportunity costs. Furthermore, sometimes I will even refuse to use a service if they don't charge money. The interests of a service will often be aligned to those who give the money. So if the money is not coming from me, the supposed customer, it has to come from someone else.
