Yep, thats the problem, a differential will send all power to the wheel with the least amount of traction. A lot of the AWD systems have this problem too.
Sometimes you can power brake it, push the brakes a little bit (or parking brake if rwd) and the spinning tire will get stopped by the brake first and transfer some power to the other. Some people who offroad 2wd's will hook up two parking brake pedals, one for each side.
Some traction control systems do this by using the ABS pumps to apply the brakes to the faster spinning wheel to get power to the others. This of course eats brakes.
I've had all types and your much better off with the traditional rwd with locking transfer case in the middle that way there is no slipping between the front and rear. Those can also help prevent wheel lock ups by downshifting and using engine braking when coming to a stop rather than applying brakes and letting the ABS release your brakes when one wheel starts to slide.
Years ago I have a little 4 cylinder 4x4 Chevy S10. Very light truck and of course all those people who think rwd can't go in the snow didn't understand how I got around, I rarely needed to put in it 4wd. Late one night a big storm hit and a highway overpass with on ramp froze up. To get on the highway I had to go up the hill and on top get in the left turn lane then start down the other side and stop at the light and wait for it to turn green before making the left turn on to the on ramp. The police were there directing traffic as everyone who tried to stop at that light couldn't and would just slide on through so the police would stop the traffic the other directions so no one would get hit. I saw them as I got came to the top of the hill motioning someone who hadn't gotten into the long left turn right away to go straight so I got in the left turn lane before they could motion me to go striaght. I pulled the 4x4 lever just to be safe and downshifted as I got closer to the light and the police stopped traffic as the vehicles in front and beside me started sliding. They looked at me with big eyes as I downshifted again and came to the stop bar and applied a tiny bit of brake and stopped like normal, then motioned for me to go on since they already had traffic stopped the other ways. I popped it out of 4x4 and started off and drove around the turn and onto the highway without any problem. The locked 4x4 won't let one of the wheels brake loose since one of the wheels at the other axle would have to do the same but it still had traction. Years later driving a newer AWD vehicle with ABS I tried to slowly stop at a light on flat ground in the snow. One wheel slipped a bit and the ABS kicked in and release the brakes and I had to go on through as the older ABS systems had a couple second release/apply cycle and the viscous coupled front and rear allowed a speed difference between the front and rear axles.
Some vehicles even with auto transmissions you can start in 2nd like a manual to get less torque to get you started in low traction.
