I'm not sure the devs stopped caring as much as the powers at be. Software development has become more commoditized than we want to believe. Devs following an agile workflow with every intent of performing multiple rounds of optimization find that the product gets shipped as soon as it approximates the thing that had been conceived originally.
It doesn't look like an immediate failure, so the less that leadership takes from it is frequently that the level of maturity they shipped is safe. The cycle continues and eventually folks lower down succumb to this shipping pattern. The only things that get them to optimize is competition that successfully drive home their win was due to performance. This doesn't always lead to optimizations when you are an incumbent who can still close more feature gaps because those often result in higher sales and revenue.
