I thought the phrase "COMES WITH ABSOLUTELY NO WARRANTY" in most open-source licenses would make it clear. But obviously no one reads licenses or EULAs. However, I would let people file issues and would just let them sit there if they are not a paying for it. This way at least the known issues are documented and there would be less duplication. Letting people fix their own problems is a good strategy. However, if you are encouraging people to send PRs, then there is a maintenance problem. Especially if some eager people decide to add major feature or refactor the code.
