Basically, unless you own 80% of the outputs on the blockchain you don't have enough to identify subsequent transactions, so any foothold you gain in owning outputs becomes rapidly weaker. Given the cost of owning 80% of the blockchain outputs, it's not an attack that is particularly effective even at Monero's current state of usage.
Individuals who publish their input history won't make any significant difference.
