Why Do I Share Different Amounts of DNA?

If you have a cousin that has tested at more than one company (23andMe, AncestryDNA, Family Tree DNA, MyHeritage, etc.), you may have noticed that you share different amounts of DNA at different companies. For example, you may share 67 cM at Family Tree DNA and only 45 cM at AncestryDNA.

Shouldn't you share the same amount at every company? If not, why not? Let's look at a real-life example!
