If suspended means they also don't currently pay, let's exclude them as well. (I'm not sure what degraded vs suspended vs non-active means), but I think the goal is to get an estimate for "active" users (and we use that they are paying as a proxy for that).
Let's exclude them since we have the users separately.
A suspended user is suspended because of spam nowadays. There's no way for these accounts to revive themselves, IIRC. They can simply be excluded.
A degraded user is a non-paying user, and should be included (stacked on top of active? could we?).
