You're reading him too literally, and in the process create a strawman. It's obvious he updates his software; Business software must be updated to match changing legal requirements, besides a nonsubscription business has nothing to sell without updates. He's saying that Windows per se did not require extra work for compatibility after he got it done since forever, while Mac needs adjustments and rewrites every once in a while, and the last time was too much for him. I guess he'd rather spend the time doing features.
