Re: So let the Open Source 'community' teach the European Community
Especially if a small outfit, such as the OpenSSL project were to craft such a license condition, then litigate once they're aware of that license being violated.
Effects: No openSSL, most e-commerce and TLS implementations cease immediately or litigation bankrupts the breeching party in the EU, complete with takedown orders for entire websites.
One needs only look for such, ahem, low impact projects to find a wrench the size of the EU to throw into their legal works. If the legislators then decide to double down and insist, introduce them to the fine folks outside who are wielding their pitchforks and torches.
