In my team people object to TS due to a few things: additional complexity, additional build step, build time increase, copy-pasting code around (to console, code snippets etc.) does not work anymore (but last time we talked it was soon after coffeescript -> esmodules migration and I guess everyone was tired of coffeescript which might have affected the mood).
There's no unanimous consensus that TS is all gold; some people who are fine with types don't like certain TS implementation details and in fact some devs start saying out loud that sometimes it's very difficult to fight TS with certain constructs.
Something that's gaining popularity and what I'm trying lately is using JS + jsdoc annotations more thoroughly, which gives the niceties of TS (when using vscode) without the downsides and heavy compilation step:
