Frankly, absolutely, yes. The owner of the system has the right to make decisions about it. It is not Canonical’s or Snap’s job to force them into certain decisions. Linux gives the owner/user the power to do things, and sometimes it’s the power to shoot themselves in the foot.
Who knows, maybe they have good reason to prevent updates. Maybe security holes are being handled by a firewall or something else external to the system. Maybe an update would break their payroll-check-printing system. You and I and Canonical and Snap can’t know the right thing for every situation.
