> It doesn't force companies at all, only those that are comfortable shipping source libraries end up adopting such languages.

Yes, and the others are left behind and don't get to participate in (and infect) the ecosystem. Sounds like a win to me.

> I used to work for a company that shipped encrypted Tcl source code and provided the necessary interpreter hooks to access the code in its encrypted form.

Surely.. if the interpreter can decrypt the code then so can the user? Minification and obfuscation are of course still possible, but the whole encryption thing seems pointless.

Tools like IDA are always a possiblity, the large majority of customers are willing to go that far.

"Infect" the eco-system? That is not the way make business.
