Most of OP's complaints come from the misuse of JQuery, including compounded performance issues when paired with a SPA framework (in this case Ember, which IIRC has a dependency on JQuery either way). Slow + Slow = More slow.
Honestly it's a library. Use it, don't use it, replace it, it honestly isn't worth a million identical arguments. People like to use JQuery as a microcosm for bad javascript practices but guess what JQuery didn't make you do it! It's just a library.
There is no real reason to avoid JQuery. Sure you should, as a good developer, explore alternative solutions for different problem sets. Maybe those alternatives become the standard for your team, maybe they don't. But unless you made a meaningful discovery that can add to the conversation, you don't need to make another blog post about it. Ugh.
