You get a perpetual fallback license even if you stop payin, which is what I was referring to. It’s pretty much functionally equivalent to what Unraid is proposing here. You pay for a first year, get a license to use that version, then need to pay again to get an additional of updates.

I get your point, but if it’s just about semantics, why would they be so defensive about it not being one?
