The trick is that the jump goes from 20 to 100 Dollar for the Pro to Max subscription. Pro is not enough for me, Max is too much. 60 would be ideal, but currently at 100 it's worth the cost.
But this is how every subscription works. Most people lose money on their gym subscription, but the convenience takes us.
What can bite them in this case though is alternate providers at the same price point that can bridge the gap. e.g. you currently get a lot more bang for your buck with the $20 OpenAI Codex subscription than you get for the $20 Claude Code subscription.
