The "like" is for the data point, not for the experience you had to endure. That completely sucks.
1.5 to 3 hours as the "new normal" for arrival/departure immigration at SGN is going all kinds of viral on social media. The Fast Track providers may be chortling thinking this will drive more business their way, but it's equally likely to have the broader knock-on effect of diverting passengers to other destinations where there is a clear definition of who is and who is not entitled to the priority immigration lane -- the obfuscation of which they directly profit from.
