Why? 1PW is succeeding. They didn’t do some huge moral quandary either that would make stopping the one time buying product a moral failing. People like the first commenter and myself have used 1PW for many years too and are fine with what has gone down.

Vs a clear moral screw up like the big tech companies colluding to not hire one another’s employees.

If they said "buy once, get upgrades forever" and didn't provide that, then yeah, that's definitely a very plain example of immoral dealing. The future service is exactly what the purchasers were buying - not a nice-to-have add-on.
