50k annually for a static set of weights is actually crazy, though.

As in - I make software for a living and they can fuck off. Produce the item. Sell the item at a cost you find reasonable. Convince me to buy it again with an upgrade that's worth buying.

Period.

There's no "service" happening here. If anything, the proposed cost model just makes me incredibly unlikely to engage at all, because it means they're going to insist on trying to track my users (a thing I don't like doing...) with whatever bloatware they shove into their "sdk".
