Web Components is a pretty niche technology and as such it really appeals to some people, and it doesn't appeal to others, and that's okay. You don't have to like it, it isn't meant to be a good fit for everyone. But for some people it might fit really well with their requirements, and they probably have legitimate reasons for that.

If I understand correctly, your criticism is that the people for whom Web Components is a good fit are publicly discussing the reasons why they prefer it over other solutions?

> pretty niche technology

The main problem is that for a "niche technology" it sure infects too many standards, requires an insane amount of new standards and makes supporting things needlessly complicated.

There are some good parts in the ~30 standards they require, but instead of just the good parts you get the whole horse, and the cart it's attached to, and the cargo in the cart.

It's not.
