Prime example of this are the Adobe CS apps. As far as my needs are concerned, CS1 or CS2 is more than enough. Very few features added since are of benefit to me, and yet I have to live with these apps becoming ever-slower, ever-larger, ever-muddier balls of mud as a result of those features being added.

At this point for some categories of apps I would gladly pay a subscription for a product that’s feature locked, with 100% of development efforts going into fixing bugs, improving performance, and keeping pace with OS updates.
