You want to sue an open source sw maker for not providing a feature for free because when you expose your ES to an insecure network without that feature you put yourself at risk ?
How about you don’t put your ES in an insecure network without buying the feature or pay someone to write the feature for you.
Your analogy is misleading and wrong, my mechanic one is better
How about this I offer you a stranger a ride to a location convenient to me for free, you take the ride then demand I drop you off at another location otherwise you will run in the middle of the road and hurt yourself
