What's the point of AS Subscription base?

the app does not offer extensive metadata like ROON what’s the point of subscribing to AS just becoz it sounds so good than ROON? why not go back to the old way sold it as a one time lifetime license then we buy again if there is a major version coming out for example such as this scenario from 3.5 to AS. once again what’s the point of subscribing bizness type of model?

you want rental apartment type of bizness where you just sit there in your couch and wait for the month to end or year ending? and you just repair the apt when some renters complain about it well that’s lazy man lol…

Because you cant listen to Metadata

Same point as Roons subscription at a guess
