Dumb question why are most printers using a hot plate and some others have no hot plate like on a makerbot?

No, good question :)

To stop the print warping when cooling, the heatbed helps reduce the difference in temp between the bottom layer and the extrusion layer.

PLA warps a lot less than other plastics, so you can get away without a heated bed if you have good adhesion. Personally I always use heatbed even with PLA.
