I don't think Superhuman should have caved to this criticism as quickly as they did. Good that they kept the feature, albeit dumbed down. People pay for a power user email client because it's exactly that - a power user tool, which should be fully featured. If you remove read receipts then there are a whole host of other email clients that will gladly give you that feature (bye-bye revenue). Is someone going to write a Medium post calling out each of these companies too? There is also a bunch of companies that aren't primarily email clients - like CRMs (Pipedrive etc) that offer this feature out the box, as it's exceptionally useful for sales teams. If there really was such mass hysteria regarding read receipts in emails (WhatsApp has it by default too?) then it should be your email provider that should be leaned on to secure their system. Google has known for a very long time about this, and has changed the loading of images to stop location tracking, presumably the only thing they actually think is controversial with read receipts.
