What I've found is that senior developers with 10+ years of experience with many different paradigms and projects tend to enjoy JavaScript and many hate TypeScript (particularly because of the build step and complexity that it brings). But for some reason Microsoft is running a lot of propaganda campaigns to promote TypeScript. My guess is that they're trying to push all the JS devs to TS and then once they have enough adoption, they can slowly start diverging from JS standards and take ownership of the ecosystem - This is an old Microsoft trick.

The scenario you are describing (TypeScript diverging from JavaScript) is unlikely in my opinion.

Orta, a member of the TypeScript team, describes the reasons why in his video "How Does the TypeScript Team Try to Avoid Negative Effects on the JS Ecosystem" https://www.youtube.com/watch?v=qr0TnQ2mHwY

It directly answers the question of "What would a malicious version of TypeScript look like" and explains why this is unlikely to occur.

I have found the exact opposite.
