And how/when did this start? Thanks.
Why do motion picture stocks use a different process than stills stocks?

They don't, particularly. The only difference is the removal of an anti-reflection backing on motion picture stocks. This was absent on some black and white films of old, which is why things like candle flames in old monochrome movies sometimes have a glowing ring around them.
Is this an essay question, or something?

No, they do use two different processes. It's not only about the remjet, there are other differences between ECN-2 and C41:

The C-41 process uses a different color developing agent (CD4) than the ECN-2 process (CD3), so the dyes formed may be different. Other process differences will cause contrast mismatch or changes in speed.
As for history:
