I don't think "this" in JavaScript was a bad design decision. The bad decision was how functions create their own scope in unexpected situations. Also, I think modern JavaScript still requires a lot of "this," just much less ".bind(this)" or "var that = this."
But the thing is, just because arrow functions exist doesn't mean people are going to use them. Similarly, just because modern browsers allow "let" and "const" doesn't mean people will stop using "var."
I agree that JavaScript is generally fine if you stick to the new parts of the language, but that in itself is a pretty big problem. Maybe not for me and you, but for software development in JavaScript generally it's really not ideal.

It seems to me that at one point JavaScript had a lot of confusing/bad design decisions but that more recent changes have largely eliminated them. For example, I almost never have to worry about "this" anymore.
I recently worked on a project using TypeScript and I really appreciated how it changed a lot of the bugs from being runtime to compile time. I could definitely see how that is a big flaw, but it seems like the community is developing solutions.
