But it's not only "old" Android phones in "developing" countries impacted.
Never said "developing countries". Said "a significant part of the world", that would include all people with old phones.
However, if you want to take that example, some countries have very poor networks, limited bandwidth. The internet is reaaally expensive. Loading external libraries can have a high cost.
I'm not comfortable with the idea of loading all those bytes for nothing, and I remember that web vitals have a significant impact now on SEO.
PS: I like this read. I don't read it at face value, it's just interesting IMHO.
From what I've read its actually even worse than that. In developing countries some phones can have a hard time parsing the libraries. This is why browsers such as UC browser are popular in places like Africa.
Much as I am always ready to be on one about using less JS, sometimes it's not entirely for nothing. PWA app shells are an example of optimizing for first time UX in a scenario where offline support is needed. Building an offline app and/or something like an image editor does have different requirements and trade-offs and a good reason to go heavier on script and care less about startup cost.
I agree with you, and it is something that I've discovered at work. The implementation must sometimes be different, and using CDN for example is not a good solution, especially in countries that do not have the infrastructure for that.
For further actions, you may consider blocking this person and/or reporting abuse

Thanks for your detailed comments.

That's a great article, yep!
