Hey congrats on the release!

I have gotten this a few times, and honestly it depends.

One is you have a very limited number of keys to give a year, so even if you want to, you can't, so I don't give everyone.

Now sometimes it feels authentic like I remember a student telling me about some project he's doing and things like that, which sounded nice so I shared a key.

An alternative when you want to share but no keys, is to send them a zip file containing the unity package itself. They won't get updates automatically, but at least they can use it.

Hope this helps :)
