All companies should do this. Sometimes I want a one-time purchase. Sometimes I want to try the program for a few months and I prefer a cheap subscription over a big upfront cost. And very, very rarely, I'll prefer the subscription, even though it's more expensive over time, to support a cool indie studio with recurring revenue instead of one-time purchases that may dry up and lead to lack of interest from the devs.

This is my argument for the Adobe subscription. One day, I'm a photographer needing apps like Photoshop and Lightroom and After Effects (because I do a lot of timelapse). One day, I'm a graphic designer, so I need Photoshop and Illustrator. One day, I'm an editor, so Photoshop, Premiere, Illustrator, and After Effects. One day, I'm doing desktop publishing with Photoshop, Illustrator, InDesign.
