Bad comparison, memory cards are a clear need (gotta have more storage space) and are not responses to poor design decisions (gotta counteract a port I use every day being taken away).
A clear need for you isn't a clear need for everyone. Maybe I have all my stuff in the cloud, so I don't "gotta have more storage space". Meanwhile I've been using Bluetooth headphones for a decade now, I have no need for the headphone port.
Don't get me wrong, I'm no Apple fanboy. But the real injustice here is that they're clinging to their proprietary Lightning port instead of going with the standard USB-C. That is complete bullshit.
