If somebody would like to have a library created specific to their needs, I’m open to doing that work.
Just because it’s open source doesn’t mean that work should be free.
A great example would be the fly.cr shard I made for fly.io:
GitHub - superfly/fly.cr: Crystal HTTP middleware to handle fly.io multi-region postgres replays.
Fly paid me to write that code because they wanted it done, and I don’t see anything wrong with that.
In a similar vein, Manas pays for open source work. (Source: Call for Crystal Language Devs! - #4 by beta-ziliani), so I really don’t understand where the tone of your message comes in.
