Why should I learn AWS instead of Azure or Google Cloud?

I might be wrong on some of this as I also have a bias..

• AWS is the most widely adopted and Dev friendly Cloud platform.
• AWS skills seem to be the most valuable in the hiring market place
• AWS is build on open source
• AWS runs a number of different programs to help people to reinvent themselves as AWS experts
• Their 200+ services are all their because of customer demand
• They are data driven rather than marketing focused
• Certification is much more simplified and generally more respected (Pro)
• AWS have a come as your are policy, rather than forcing you to adopt their closed source software.
• AWS documentation is second to none
• AWS enterprise support is the best around
• Attending reInvent can be life changing
• The AWS community is an amazing space to be in
