Spot on @Schurkey.Yeah. There's not much point to calling, I think we all know what the answer will be.
Not that the answer makes much difference, because the Federal Trade Commission which should be monitoring/regulating this, is more of an industry lapdog, than a consumer watchdog.
Wild Guess: The distributor housings for pretty-much all of these distributors are cast and machined in the same Chinese factory. Notice that they've all been cut for O-rings down by the distributor gear even though GM never did that.
I think they're all or nearly-all coming from the same factory, and MAYBE some resellers are putting better modules and caps on them (or maybe they're just putting fancy stickers on the junk modules.)

Messaged them about an hour ago. I guess if you’re not actually manufacturing distributors you have ample time to respond to messages.
