I regularly check the 'Your Purchases' list to see whether there are updates available, and find it best simply to click on the 'Last Updated' title to bring the most recent updates to the top. That saves scrolling through the rest of the items unless, exceptionally, I need to download something again.
I don't have all the available software, but my list suggests that the logic may be as follows.
(a) Discontinued software could still be in use, and one might need to download it again if a hard drive failed.
(b) Other software seems to have an expiry date for free support and upgrades where under the 2019 licensing arrangements ( https://www.coffeecup.com/help/articles … ng-policy/
(c) Products not under the 2019 licensing arrangements, but not discontinued, are presumably still supported without annual subscription, at least for the time being.
