Indeed. If someone is going to argue credibly for treating everything from commercial sources as spam then they also need to explain how businesses can provide any information they are actively required to provide to their customers either by law or by whatever method the customer is using to pay them. In general the merchants have no say in this and the penalties for failing to provide the information can be far mor…
It is their choice to pollute the channel they use to communicate with customers with spam. They don’t have to send spam, and if they offer the option they shouldn’t make opting out difficult or dark-patterned. Same thing with crying wolf and all that.
It doesn't matter to those people whether there was a quick and easy way to unsubscribe or change preferences. It doesn't matter to those people that they actively requested that kind of mail a few months ago and have forgotten. It doesn't matter to those people that they might end up blocking important messages they do want later. It doesn't even matter to those people that they're flagging information that is required by law to be provided to them. There is no nuance here. Got mail. Hit "spam". Done.
Some of these people even think that marking the transactional "thanks for your payment" mail as spam will somehow end their subscription to your service or get them out of a long-term contract early! Then they'll issue a chargeback that is also totally inappropriate and in violation of contract and claim that they gave notice to cancel by "unsubscribing" from the emails by marking them as spam.
Dealing with customer support for those people is not fun. In a perfect world it would go both ways and we could have a system that notified us of such behaviour immediately so we could choose not to do business with those people in the future. It is as sure an indicator of a customer who is not worth the trouble as I have ever found after people attempting actually criminal behaviour.
Spam is a difficult problem. Obviously a lot of senders really are abusing the recipients in ways that are not welcome and should ideally be stopped. But there are plenty of recipients abusing the senders of legitimate messages too.
