Emails from companies already have a unsubscribe button. So if I unsubscribe they shouldn't send me emails. That is not changing with the new Apple Sign In feature. Emails will still have the unsubscribe feature. The only reason for devs to push for a real email is to sell it to advertisers. They are not deleting the email once I unsubscribe. So giving them an ankoymized email is good. I hope this succeeds.
Many spam emails I get these days from companies say things like "Unsubscribe from this list" so for example I have to unsubscribe from their "Daily Digest", "Weekly Digest", "Recommendations", etc. all one at a time.
And there's no guarantee how many of those "lists" you are on with some softwares. You might have a one-click unsubscribe, but you just one-click unsubscribed from the first of 100 lists you were placed on for that company.
