i believe not having a subscription model on an app is greedy and unbefitting of extended consumer use. you expect someone to charge a dollar for weeks or months of work then support you with issues/help/continued updates the rest of your lives?
Do you pay a subscription for MacOS? Do you pay ANYTHING for MacOS? No, you don't. The last version of MacOS that was purchasable was Mountain Lion. After that, they were all free, and supported for the rest of the lifecycle.
Yet here you are, getting support, help, and continued updates for the duration of the lifecycle of the software.
You are effectively contradicting yourself here, not only with MacOS, but with any Apple product you have. Same goes for any Microsoft OS you run. Any non-365 version of MS Office. Heh.. I still got updates for 1Password 6 after doing a full TM restore to my MBA.. you know, something that they stopped supporting 2-3 years ago.. and that Time Machine restore was a little under 3 weeks ago.
Guess you better switch to Linux.. oh wait; CentOS, RHEL, Slackware, Ubuntu, Debian, SLES, and others do the same, or more: they do it for free, with that continued support.
FreeBSD is the route fo... wait, they do the same. Solaris... nope, same thing.
Guess you're stuck not using any applicable OS nowadays, because of the same thing, and none of them require a subscription.
