Kind of? It's certainly companies actively moving towards shittier services at the same time as others, but I don't think it's as much of explicit and intentional collusion as it is high school clique prom politics and VC money drying up post rate hikes. There's more of a focus by investors on generating profit over growth at this point because money is no longer free. The safest play for a lot of these boardrooms is to not stand out as a company not realigning priorities to reflect this.
Facebook did layoffs? Okay we have too as well or we're not in the same big boy class as facebook. ... See? We're safe, money please
