Yes, every attack that qualifies gets sneak attack damage. That being said there are scenarios where only the first attack qualifies for sneak such as attacking with a bow from cover, or successfully feinting in melee.
If you have Greater Feint or Improved two weapon feint, then the all attacks are sneak attacks after a feint.

The sniper-archer still has a chance to maintain cover, albeit at a -20 on the Stealth Check. Also, there is a way around that. There is a Rogue Talent, False Attacker, that allows the Sniper a Bluff Check. A successful Bluff Check means the target thinks the shot came from somewhere else, and the sniper doesn't even need to make the Stealth Check.
That being said, your main point is correct, under certain situations, the first attack does negate the benefits of Sneak Attack for the rest of the Attacks in the Rogue's Full Attack.

The important note is that if you're using stealth to achieve sneak attacks, stealth breaks after the first attack and will thus prevent you from gaining additional sneak attacks. However, if you have a method of qualifying for sneak attack (such as flanking) then all attacks made with that qualification will deal sneak attack damage.

There is no limitation on the number of attacks per round that can benefit from sneak attack. There are situations where attacking causes subsequent attacks to no longer qualify for sneak attack, but that's not the same thing.
Classic examples of getting lots and lots of sneak attacks in one turn include full-attacking a blind creature, full-attacking a creature while affected by greater invisibility, full-attacking a flat-footed creature, and sniping.
Classic examples of an attack causing subsequent attacks to no longer qualify for sneak attack include attacking from Stealth (without sniping), attacking while affected by invisibility, and attacking with a spell involving multiple simultaneous attack rolls (e.g., scorching ray).
And as mentioned above, attacks of opportunity, like any other attacks, can result in sneak attack damage if the qualifications are met.
