Agree, I made the same experience with a project that was migrated from JQuery to AngularJS and was updated to Angular just one year later, the ROI was super negative. And I face this problem everyday with older projects that use old tech-stacks. People always discuss about new technology, but in many cases it does not really make sense to migrate, especially if client does not care.
I myself used Vanilla JS for years because I did not like JQuery. I skipped Angular, tried React but did not really like and now I use Vue. So my receipe is:
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
