Including advertising in a paid product should be punishable by public flogging.

What ought to be the punishment for falling for the line that paying for something means no ads?

Who says we're falling for it? I expect it, as in I believe that's how it should be. I know that offerings can change and that there are paid services that include ads. I know what I'm getting if I sign up for a paid plan with ads. I also think anyone who offers such a thing should be publicly flogged.

Why? It's a new tier that's lower-cost than the current paid version.

Don't care. It creeps upward. And even if it doesn't, it's terrible.
