We choose to have beta testers who choose to opt in and even if we give them access to the beta server, they’re under no obligation to ever download or play it, and even if they do play it, they’re under no obligation to provide feedback or report bugs.
It’s a nice way for us to give some players a sneak peak at upcoming updates, a little more insight into the development process and get some player feedback before the update goes live.
We have paid QA testers for the actual bug testing - that’s not what beta testers are for, although we’re obviously grateful for any and all contributions the beta testers make to help us make a great game. Beta testing isn’t a full time position being taken away from any past, present or potential employees.
