What does Porsche have against the LSD?

PSM only comes back on ( if you manual disengaged it) if you brake hard enough to activate the abs , smooth non panic braking won't turn it back on.
Late PSM 5.7 will cut throttle if it detects the car is in a full on spin . Earlier 5.3 PSM won't .
My car is a later one , it does better doughnuts if the PSM is turned off first .

It is a falsehood that PSM reactivates when you hit the brakes. PSM will reactivate if it determins you are an assclown, though. I have had a single instance where mine came back on - after a series of pathetic fails to catch a spin that resulted in even more tire-smoking spin, but otherwise it has stayed off when asked to do so.
PSM can retard timing and/or cuts throttle in addition to modulating the braking. The system is fairly smooth - I've only felt it a few times under acceleration when one tire loses traction. Compared to the ASR (active slip reduction) equivalent in my Corvette - which is about as subtle as a snapped drive shaft and makes a loud and very unpleasant noise under the hood when it's working - the 996's PSM is subtle and light-handed.
Note that I cannot comment on how PASM works - my 996 is too old for that fancy 33% longer acronym.

In porsche 996 the essential companion , it states the PSM comes back on if abs is activated in hard braking.

It's not that hard to try it yourself and see
Good article on PSM

LSD and PSM, PASM are really not required on a 996. Get a proper suspension setup and you will have no trouble keeping up with a newer GT3. I say that from experience. I think these were big selling points for new drivers who want to floor it with the wheel turned during hard rain.
