Confused why it costs to lose a feature?

I'm on a shelf hosted community edition of N8N and do around 50k executions a week.

I like to pay for a service if I enjoy it, but whats put me off is if I buy the business account, I will lose me unlimited executions and it will be downgraded to 40k a month?

So why would I pay £589 a month to run less (Yes I know it gives you more features) but why cant we keep the unlimited executions?
