In my opinion, political spin or rhetoric is only a danger to very lazy people. If you're prepared to accept what you're told at face-value, then when you read on the news that there was collateral damage in a bombing of Iraq you can mostly ignore it. If however, you're the type that actually researches recent events and stays informed, a civilian massacre is going to shock you just as much no matter what they call it.
On the subject of the language itself changing, it does that. There really isn't any point getting upset that 'layoff' is the new word for 'mass-firings'. They're talking about the same concept and as long as you recognize that, the news is just as relavant. Is 'layoff' a lighter term than 'mass-firings'? Sure. Theres an undeniable aesthetic difference but functionally the words serve the same purpose.
As for 1984, political correctness is irritating but its a long way away from that. Media can get as kid-friendly as the Barney show but political correctness will never actually eliminate concepts. It will never become improper form for a news station to report that 30,000 people have lost their jobs last year. As long as that remains the case all we need to do is remember what they're calling 'firing' these days.
We're also infinitely far away from not being able to express concepts of revolution or discontent. Honestly, I don't think that day will ever come. There might be a day when you can't say 'fuck' on television, but when that day comes they'll have a new term with the identical connotation and usage. It'll mean less to us, but for the younger generations that grow up accepting this new word as 'fuck's replacement, it'll be just as meaningfull.
One wonders if shakespearean citizens of yore we're equally diturbed by the increased restriction on "Slithe" or "Zounds". Those we're curses, way back when. Does anyone honestly feel the language has been cheapened by having them fall out of use?
tl;dr
If you stay informed and know the facts it doesn't matter what words other people use to describe events. The language changes pretty much every generation (You're kids will think you talk like an old person. It's inevitable. Because you'll be talking like someone who was born in the 90's). One word for fuck is as good as the next. There ain't no point worrying; so long as you have a free media, how it chooses to express itself is superfluous.
Should people be paranoid about the language? My general advice would be to assume things are generaly going to be screwed and there's nothing you can do about it, but that everything is going to work out well and you don't have to do anything to ensure it. I don't know quite how that applies to this topic specifically, but it's how I lead my life and ... Well it keeps things interesting if nothing else.
