We all root in different ways - how boring would life be if everyone thought the same way!
I tune out anyone who leaves via free agency - Grant Hill, Alan Houston, Morris, Parish, Gibby. But if a player gets traded, sometimes I still follow. I was happy for Stafford when he won a SB. That's since faded, and ultimately he is part of the enemy now. And I watched every game that JV pitched in Houston in 2017, and I was glad to see him get that ring. It's faded since 'bang a gong' was revealed. I followed LeFlore after he was dealt for Shatzeder. I played high school basketball with Loy Vaught, and followed him closely during his non Pistons years. I even often choose a New York slice over a Detroit style slice. Exceptions - I will loathe anyone that playes for the Yankees, Dodgers or Red Sox, regardless of Detroit bloodlines.
