I haven't seen the tweet, I'm not going to look for the tweet but releasing someone over liking any tweet is ridiculous when you consider what players have done over the years and manged to stay employed.
I'm not just talking about pre-segeragtion days.
Of course it being hypocritical doesn't mean it might not happen.
I can't post the tweet because of strong language including the n-word, but it's easily found if you search Twitter. There are screenshots proving he liked it. I sure hope it's accidental. If not, it's devastatingly disappointing and I expect he will face pretty severe consequences.
