It sounds silly since nothing really changes, but it has to do with the way investors calculate the value of public companies.
What you are saying might be how it turns out in the end, but it is not a given.

Split up each business could be valued with direct competition in market and the same PE ratios applied to evaluate value and market cap. It caused a noticeable jump in overall stock value while nothing actually changed other than how businesses reported to the market.
If the units all get too independent, based on my view at ground level in China, is that they will all get more powerful in their respective markets. Nobody was happy with the value erasure.
On the other hand a fuckton of value has been irrevocably erased - entire ed tech sector isn't coming back to pre crackdown levels. If anything CCP hasn shown little regard for crippling soft tech since it will redirect talent towards strategic hard tech where job and wages have been booming. Baba getting proper rectification if it incentivizes future talent to reorient towards SMIC seems to be part of the plan.
It's demise is a self reflection on the beyond limit of control that has to be relieved for the long term stability
The ed tech industry's value is about meaningful as the scam industry
