From a purely practical angle, how am I to ascertain why they chose Apache 2.0 as the license and how should I weigh that knowledge/guess against the crystal clear grant terms of “Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform, sublicense, and distribute the Work and such Derivative Works in Source or Object form.”?

If I license any of my code under that license, I hope someone builds a billion dollar business on it. If someone else does the same, how should a licensor understand the difference and act accordingly?
