This is just ridiculous.

Open Source is about just that - allowing anyone and everyone to have access to the source and (if free) making their own version.

There never needs to be justification to write something from scratch, even if it's been done a million times before.

You can appreciate open-source, you can wish that proprietary code was open source, but you never have the right to tell people what they should do, nor are you ever likely to be correct as to what they should do - you are not them.
