What is the purpose of sharing this? To highlight how many devs are affected?

Perhaps to avoid buying them?

I personally have a weird habit of uninstalling and reinstalling games a surprising number of times. If I know there’s a fee associated with it, be it for the dev or Valve, and the money goes to vultures at Unity, I won’t be buying.

that’ll probably hurt devs more than unity.

To avoid re-installing them then, if we’re going to play by the stupid rules. Just install it once and never ever uninstall it if you have even a slight chance to play it. Also make sure your disks have multiple backups.
