this is the first meme I have ever made (yes I am that old) - so be gentle :)
what does being modern mean to you?
Prusa still let's me sneakernet the print file to it, it'll do it over the LAN, but USB is faster. I'm the only one who uses it, but I'm pretty sure since they're focused on user experience it wouldn't be onerous
M5 needs the printer logged into their server, needs the user authenticated and has no USB slot
