Here is my area where we have heavy clay, the soil tends to be very alkaline, so adding gypsum only makes the soil more alkaline -- not a good thing.

That's like saying "This stuff will stop you from bleeding to death, but it may also cause the wound to heal with a bit more of a scar".

Some people have clay soil that is so totally out of hand that altering its pH for a season or two is something worth dealing with, if the gypsum otherwise does its job.
