Which is fine, isn't it? The way I see it, there are 2 options: either you buy software "as is" and can use it forever, but you don't get free access to update

Which is fine, isn't it? The way I see it, there are 2 options: either you buy software "as is" and can use it forever, but you don't get free access to updates (or get them up to certain point of time), or you pay for a subscription. People who bought old versions of Pixelmator or Photoshop or 1Password can still use them (I have 1Password 4 on one of my devices), as long as the system updates won't render it useless.
