For me personally the snark isn't because their SRE team is incompotent. It's because software that tries to be everything to everyone is inherently terrible. It's not fun to use for the users, and so many compromises need to be made on the technology side to make that happen that it ends up just being crap all around. This includes Salesforce, SAP, Dynamics, any platforms like that which scale many industries.
Flexibility and abstraction come at a high cost. It doesn't really matter though, world domination at all costs is the name of the game.
