Try reading the top of the page. There's your explanation. The physics of contrails didn't change one bit. The technology changed radically.

It always makes me shake my head when people totally ignore other sources for things found and point at aircraft as the cause. Aluminum and barium, which are usually the two most common substances claimed to be sprayed are common in ground sources and industrial processes. I've driven past powerplants and factories leaving exhaust clouds you could see for 60+ miles. There's no way in hell those are 100% clean.

A lot of people don't, but the only options are j to get the military to release their contrail suppression, which has about as much chance as the sun rising in the west, or giving up air travel until they can solve it.

No, but the military has ways to reduce contrail formation. But they're not going to release it to the public any time soon.
