does this mean that only the person who initiates the position (either by writing or
buying the option) is the only one who can decrease the open interest that he/she has
generated?

Will, this is my understanding of OI, I believe you are half correct:

x = total number of new contracts written
y = number of contracts closed out by original writers

OI = (x - y)


FUZFO,

This may sound a bit like semantics but the first sentence is truly accurate. No one can decrease the open interest that he/she has generated. Others may change open interest by increasing or decreasing contracts they generated but the contract you generate will always be open until you close it.

The bookkeeping is such that the total open interest is tabulated as one number so your OI=(x-y) equation is the number one sees.
