That depresses me because it's clear who is being ignored here: the user.

A 3MB bundle size instead of 1MB does make a difference, and if you're working on the kind of site that relies on conversions/purchases to succeed then you're absolutely leaving money on the table. Not to mention that Google factors in page load time to rankings.

> our UX was worse than our competitors

If your competitor has a < 1MB bundle and yours is 3MB then any user on a low end Android phone is absolutely going to have a worse UX experience. Maybe stakeholders aren't aware of all this. Maybe you should tell them.

Most of the apps I've worked on don't have conversions and aren't indexed by search engines. One app I worked on recently did have a mobile version that received a small fraction of all traffic, and even then overwhelmingly from relatively modern iOS devices.

It's like all engineering: use the right tools for the job. If low-end Android users are a significant portion of your target audience you have to design your system around that.
