I think the accusation is fair. After all, Google did dump AngularJS entirely into the trash with the incompatible release of "Angular" (without the JS) when they realized what a monster they had made. Like the author says, all of the layers of services, factories, etc. just made it unnecessarily confusing without adding any utility.

Google also started the Polymer project which became Lit, which is the antithesis of Angular: all of its benefits with none of its cruft. If Angular ruined JS, Lit saves TS.
