Where is the Freedom of Expression in Social Media?

Just the other day I heard a news on Fox News about an employee got fired because of her Facebook status update about boss' salary. Then last Friday Willie Revillame rants on TV about suing people who express their opinions on Twitter regarding the Jan2x issue. And then just last some people rants hate tweets to Tim Yap for tweeting the Binibining Pilipinas 2011 winners in advance while the said event is airing in progress in ABS CBN. Some people said Tim Yap intentionally post the spoiler to spite the rival channel where Tim is currently working and some said for publicity. For me, I actually don't see any wrong on what Tim did because the fact that others who have seen the coronation night in Araneta also tweeted the results.

Around 82 people who were in Araneta tweeted the winners earlier. Blame it to ABS-CBN for delayed airing. Twitter is real-time.

And why is it during Manny Pacquioa's fight and others tweeted earlier for the results nobody rants about it as spoiler? hmmm.. thats odd.
We should remember that celebrities like Tim Yap are people who also has the freedom to express what they want to say on their own social media accounts as long as they don't abused it.
People has so much hate to express but not much love to give... Why not do the other way for a change? You will not just free yourself from stress but also contribute in world peace which exactly what we need right now. In addition, if you dont like what he/she is expressing then unfollow or unfriend them. Dont waste your time hating others for their status updates and opinions. Express what you want to express but stop hate attacks! There's a lot of other important things to worry about yo...
