My opinions (if anybody cares):
No *speech* should ever be outlawed (what ultimately makes disgusting speech
stronger with the argument: "we are right; that is why they censor us") in
the public space, Internet included: anyone should be allowed to write/say
whatever (s)he wants on his/her *own* site/newspaper/radio or TV
channel/etc.;
Google/Facebook/Twitter/etc. can apply, on *their* sites, any rule they want;
If those rules involve editing/removing content, then
Google/Facebook/Twitter/etc. should be considered "editors" and be held
responsible of anything written on their sites (like newspapers' editors);
No law should ever apply to a specific set of corporations (doing so - but
does it? - the EU implies that Google/Facebook/Twitter/etc. are the whole Web
and that they are in charge of its governance);
