i also want to mention Donation based/ads(if not too intrusive) are also fine ig.
and sometimes(depends on country) your only option is monthly subscription (whatever its rent or internet price) you can find for sale buts its like in the millions and i think internet price is monthly only.
but yeah i dislike monthly subscription as much as you(and i agree with you)
i could use a Freemium service that has a monthly subscription too,but i wont buy the subscription. (i may abuse free trials kek)
but obviously i prefer perpetual license the most.
