People will replicate it, sure, but supporting it regularly is another thing. I guess the majority wanted a perpetual license - so it's a win for the masses.
defensibility nowadays is app support and development. the more work you pour into it the more defensible it will be.
I personally would gladly pay to have app constantly polished and improved. What I would not use is some vibe-coded alternative that was slopped with AI in a day and pushed to github with a tweet "i made a free X alternative" and then abandoned.
I'm not paying $40 for a taskbar replacement. And not for two years of updates and a two device limit on top.
Maybe if it was $10, I could consider it. Prices for macOS apps are insane in my opinion. Everyone wants to charge yearly or every two years now too.
but isn't that it?
