Given that the only TSA reference in that article also mentions the Bush administration, I would hope there is more up to date information now. I wonder why EFF has not updated a top level issue page in so long.
The article may not mention the TSA by names but if you were in doubt about the entities that you could encounter at the US border then probably the article wasn't meant for you anyway.
Maybe the parent poster means US Customs and Border protection? That’s different from the TSA which could potentially search you leaving the country, or on internal flights.
Fair enough, for travelers the distinction is useful so let's spell it out: TSA: the guys that mess around in your luggage, make you throw away your water so you can buy new bottles at 5x the price as well as your nailclippers. CBP: the guys that check your passport and possibly your fingerprint, take your picture and invade your privacy as much as they feel like.
Both of these can be found at US airports with international flights(and most countries have equivalents). Going on an international trip you will encounter both, for a domestic flight you will only deal with the TSA.
The EFF article is aimed exclusively at people crossing the border so it about the CBP, not about the TSA. If you never leave the USA or never travel to it then you will encounter none of this.
