Then why do you need to persuade people? Why are they unwilling?
Obviously they stand to lose something or they would 'comply' of their own.

I don't agree with you that Log4j 2 is worse than Log4j 1. Log4j 2 is a

That is precisely the sort of stuff you get when your application or newer

effort to "persuade" others in joining you when you have not really
improved things ;-).
