As well as Grindel, the 29-year-old highlighted the actions of politician Bernd Holzhauer who called Ozil a "goat-f***er" and Chief of German Theatre Werner Steer who wished for the footballer to "p*** back to Anatolia".
The 29-year-old, who was part of the German squad that exited the World Cup in Russian Federation at the group stage, felt he was singled out as a scapegoat for the failure due to his Turkish heritage and the Erdogan meeting in May.
The way Ozil has been treated by German media, politicians and especially the DFB has caused him to make the "difficult decision" to announce his global retirement, saying that: "I now feel unwanted and think that what I have achieved since my worldwide debut in 2009 has been forgotten".
Ozil has won 92 caps for Germany since his debut in 2009, scoring 23 goals in the process.
"I used to wear the German shirt with such pride and excitement, but now I don't".
He added: "I am German when we win, but I am immigrant when we lose".
The Arsenal star broke weeks of silence on the issue Sunday, posting a statement in English on Twitter in which he said the photo "was about me respecting the highest office of my family's country" and had "no political intentions".

Ozil and Gundogan were booed by German fans in pre-World Cup friendlies after posing with Erdogan in London.
He also said several of his commercial partners abandoned him during the media storm, including an unnamed charitable partner and his former school in Gelsenkirchen, who cancelled an event he was set to attend before the World Cup.
Both players are of Turkish descent, but were heavily criticized at the time over apparent divided loyalties and for also meeting a leader whom the German FA later described as "not sufficiently respecting" the values that it stands for. The statement didn't mention the car-maker by name but made a scathing reference to the German government ordering the company to recall more than 200,000 vehicles because of unathorised software devices.
"Whatever the outcome would've been in the previous election, or the election before that, I would have still taken the picture".
"This is all ironic because a German Ministry declared their products have illegal and unauthorized software devices in them, which puts customers at risk. What does the DFB have to say about all this".
