Benefits of Open Standards

Having been introduced to Open Standards, I think the top benefits of using Open Standards is that, for the part of the developers, they have all the rights to improve and enhance a particular software since it is "open standards", meaning, they can do whatever they want to as long as they will meet the requirements for the open standards। Eventually, the end-users will then have the all-access privilege with the finish products of the developers for a minimal cost and much better, downloadable and for free.
