Alright, it's fine for a company to remove features, if they are honest about why they are doing so. It's obvious none of the reasons given are due to user complaints. The truth is, they are removing SMS because they don't own the SMS platform (e.g. it's not a walled-garden like WhatsApp). Would it kill them to just be honest? Yes, it's less secure, but no end-user is saying, "Please remove SMS as it's not secure."
