Depends. I used to have close to zero software subscriptions, but now I earn a little more and I can afford to pay for some software even if I technically could do without paid version - e.g. Duolingo, Evernote, Feedly, etc. I do it as a conscious effort to support apps I use - in part so that people that can't afford it still could use the free versions, and so that they continue to exist in general. From pure financial optimization angle, I am likely wasting my money. But I think it makes more likely the apps that I use survive and stay alive, which IMHO is worth a small investment even if I do not use too much of the paid features.
