I used to love PSP back in the day. Is it still any good? I don’t much like Affinity Photo and unfortunately Adobe is completely insufferable.

Another, more current, example is the audio workstation Reaper. After the generous 60-day trial it keeps showing a message about it on every startup that cannot be dismissed for 5 seconds or so, but otherwise remains fully functional.

It’s great and one should totally buy it, of course. Doesn’t break the bank either.
