Yeah but this is like eating an entire plate of free samples then asking for a refill. It's technically allowed but you're ruining for everyone else.
Then, someone starts selling apple sauce and it makes lots of money.
Now the wizard wants to get rich too... but their sauce isn't good enough, so they try to lock down the spell. People get upset. They helped improve the spell, why should the wizard get all the money? Or their livelihoods now depend on the spell, why are they suddenly forced to pay?
Now the apple guy decided he's going to stop playing that game, and starts supporting/improving/evangelizing a restriction-free apple incantation.
Story to be continued...
A company turned a modest profit? Say it isn't so!
The guy who wrote ElasticSearch created a company to finance the development of the project. For most of their history, they released their source code under a permissive license in good faith. Amazon abused that good faith, so now Elastic continues to make the source code open and license it freely to customers and the open source community (just not competitors).
I've got no beef with Amazon, but you're kidding yourself if you compare them with Elastic in terms of ambition, greed, commitment to open source, etc.
These debates go back decades.
