The wording could have been more clear: Instead of "what you'll pay" it should have said "what your organization will pay".
Everything else about the e-mail is clear that it's about the organization, though. I don't know why this person would think they're going to start getting bills "per committer" of the organization where they're not already the responsible party for billing. Like GitHub just decided that they're going to start billing this one person for every committer in the org, but only for this one feature?
Sending a billing notification to someone who has no billing information on file, but is part of an organization where someone probably enabled that beta feature ("You're receiving this because your organization is using the GitHub
Code Quality public preview.") isn't a shakedown.
Did you even read the email? It's an extremely boring standard billing notification that explains exactly why that person received it "You're receiving this because your organization is using the GitHub Code Quality public preview." and when it would be come into affect.
It's not a small print somewhere, or one of these weekly app store subscriptions that run up high bills because someone clicked "Yes" in a game.
It's like calling a Netflix renewal email a "shakedown" just because they send you an email giving you a heads up that your trial will convert into a paid subscription.
You're making my point here - this sort of corporatist, bait-and-switch-if-you-dont-opt-out behaviour is illegal in many countries, Netflix got spanked for it this spring.
That featur is opt-in: someone had to check a checkbox somewhere to enable it.
And yeah, that how the businesses work: you opt-in to feature, then you start paying for it. Sometimes the latter part is delayed, in which case it's a good style to send heads-up email about it. Nothing unusual or scammy about it.
I was thinking the same thing, but I think it's down to this person not actually using the thing that GitHub are saying is moving to a paid service. It's hard to stop using something you don't use.
