I’m confused about what any of this has to do with what you quoted? It feels like you missed my point entirely.
Thats because of a mistake i made, the reason i quoted it and the text i did type, at some point i reorganized my post but removed that section.
But in short: they do it because some of them because of the work they did, did get some special discount codes, and potentialy using those even gives little bit of money to them. Its a very common early adopter thing companies do.
Fair and softly goes far - maybe do both tags and sections?
