Well, I think it’s more Proton just doing things as they want to. Simply not doing your way or another way doesn’t mean it’s what you think or feel it is. And yes, I remember those discussions well and you’ve always made your point clear. But should Proton do better and provide more options in different ways? Absolutely.
That’s why I explain it as one subscription but only with the services you want (custom plans). When you say multiple “subscriptions” for one account, that may confuse folks. It’s a semantics issue mostly.
