Get where you're coming from, but I don't think they're entirely wrong. Whilst you can't buy Photoshop once now (your point), there are plenty of models where the choice is still there. Netflix and Spotify both have one-off purchase equivalents. You can still buy Jira as a one off purchase instead of SaaS.
Please describe how Spotify and Netflix offer these lifetime price one-time purchase options.. quite well hidden in their exclusively subscription pricing
