Methinks you can count on Europe to eventually get this right.
Twitter getting sued and losing to France's Jew student union over obnoxious hashtags is just the high profile round two of the same joust they had with Yahoo over nazi artifacts getting auctioned over a decade ago. They won last time; they'll win this time. And US companies will comply to French law on this matter just like last time. I suspect that the pitiful €1k/day fine is going to quickly balloon to obscene amounts of money until the courts get a reaction from Twitter.
In Germany, users are suing Facebook over the right to get deleted, and while they were the first, in typical German grassroots achievements, they no longer are the only ones. This is simply going to win, and they're just getting started. Sure enough, the Irish subsidiary is dragging its feet to comply. Presumably to Zuck's despair -- here's a continent with over 600M people willing not only in fighting for the right to be deleted but also in actually enforcing it. In the end, sane views will prevail, and the US laws will get kicked back across the Atlantic where they belong -- for US citizens to debate further, hopefully with new, more enlightened insights.
The same could arguably be told of countries like China, Egypt or Iran: ironically, US firms are made to comply with local law over there, plain and simple, much faster then they are to EU laws. But the EU is hopefully similar enough to the US that the latters' citizens will not shrug that the former are merely uneducated barbarians when their laws are sent back for review.
