$100/month isn't much for developer tooling. If you add up how much I spend on hardware upgrades, other SaaS products like backup services, software licenses, and other things it's easy to justify $100/month for a powerful tool.

I pay for my own AI provider subscriptions because keeping work and personal strictly separated is important for me. I do know some people who secretly pay $200/month for Claude and use it at their job even though it's not approved. I do not recommend doing that, but it shows that some people value this for their work.

For developers earning more than $10K per month, spending less than 1% of salary on tooling to make the job easier is easy to justify.

I too spend over $100 on drugs that make me feel productive but actually am not.
