I’m totally OK with this, but having 2 pro licenses I may be biased.

It’s no different from other vendors that offer a year of upgrades with a license and you need to pay afterwards.

As long as it never moves to a “pay periodically or your entire license becomes inactive” (like Adobe), I have no issue with it.

They need to have a gentle way to handle upgrades after the included “timeframe” that also isn’t just “buy a new license if you decide to skip updating for a period of time” for whatever reason. If you stop updating for hardware or personal reasons for a few years, getting back up to date should still be competitive vs buying a new license.

UnRAID is absolutely worth it. Definitely the best computing investment I’ve made in the last 2 decades.
