I fear this isn't any step forward, but yet again doubling down. If they stayed the course with the longer quarantine period combined with massive amounts of vaccinated sheeple getting Covid, then they were on target for major backlash from the people who followed the pied piper and got vaccinated and still somehow, mysteriously, still got Covid. And because they followed the pied piper before they would again, leading to massive quarantines across society, leading to more damage and ultimately to a WTF moment by the left-stream media. By shortening the quarantine period they reduce the risk of that blowback happening (and reduce the potential impact when it does happen). But I do not see it as an "a ha" moment on their part, just self preservation and risk reduction and ultimately doubling down.
