Surprise surprise, the largest cloud provider wants to attack the 2nd largest provider.
Stay tuned for arguments as to why new laws are totally necessary to keep a fair playing field for "everyone", that just happen to serve the most dominant provider best!
Zavery said that AWS does not pose the same anticompetitive risks as Microsoft despite having a larger share of the cloud market because AWS customers don’t face the same licensing restrictions.
AWS has their own lock-in mechanisms. AWS pushes you to use managed services and AWS-specific objects which would require massive re-architecting efforts to port any mature AWS environment over to Azure or GCP.
Of course I'm sure Amazon would respond with, "But users don't have to do that!" to which Google's statement about Azure applies equally-well:
“[once locked in, users have] no economically reasonable alternative but to use ~~Azure~~ AWS as their cloud services provider, even if they prefer the prices, quality, security, innovations, and features of rivals.”
