Good question. You can go through my posts to see if I rated him or not -- even during the times he'd be relentlessly mocked for his bottling feats. He was always a generational talent who was bound to have this success in my eyes -- even without clostebol.
For the question, no I didn't like him before. I didn't dislike him either (did have issues with the legion of obnoxious fan accounts of his as do several others here). Post the scandal, let's just say that it's easier to say I don't particularly like him. When the world criticises a group, there's a tendency for said group to become cult-like and the already cult-esque fandom has only grown worse since the scandal.
I'll continue to not hide my displeasure at what's happened and indeed, this is a uniquely Sinner situation. Personally me and an IRL friend like Nicolas Jarry because despite his doping, it wasn't close to being the cover-up stinkfest of a scandal that this Jannik story has been.
Had Jarry escaped ban, continued to play during investigation, had the same layer who is working against Tara Moore on an accidental doping case, call himself a victim through PR, passive aggressively say who his reAl friEnds are and had a legion of fans coming together to form the worst fanbase on earth, my sentiments on Jarry may have been different after the doping.
But to be fair to Jarry, he served his time, and didn't insult the intelligence of the Tennis watching masses the way the Sinner coterie has.
