One can wax lyrical about the implications of this WaPo exposure, however any comment made now, would be in fact classified as Post Mortem. One can only imagine how furious Netanyahu and the Israeli intelligence community would have been at the time the ring was uncovered.
“Israeli anger at the deliberate compromise of its agents may help explain why Prime Minister Benjamin Netanyahu became so entrenched in his refusal to apologize to Erdogan about the May 2010 Gaza flotilla incident"
Livid may be the key word here, but anger within the “community” will always get vented with practical pro-active action. Blowing a friendly isn't accepted practice and remains inexcusable and Taboo. Tit for Tat is a numbers game, meaning that one can be assured that lost assets to one side result in an unequal and opposite reaction from the offended party.
With this WaPo ‘ex post’ exposure, a quick scan of Google news articles does reveal traces of ‘ex umbra in solem’, where Turkish “nationals” are concerned. The biggest impact by and large that Turkey has faced since this incident, would almost certainly concern the reputation of those concerned with this directly, namely the Turkish intelligence chief, Hakan Fidan, and Erdogan himself.
So, how would this item be connected to this story?
Update: some speculation by Ron Ben-Yishai on the identity of the agents betrayed, the man close to the military and intelligence establishments.
