C++ was not intended to be "opinionated" in the way that you believe; consider taking a look at Bjarne Stroustrup's "Design and Evolution of C++", or just his presentations at CppCon conferences over the past several years which focus on the history of the language.
Now, it's true that C++ has seen significant changes, but:
1. C++ is, indeed, a multi-paradigmatic language; and in recent years it is becoming easier to write code using other paradigms - particularly functional. But your old code, and programming style/paradigm, still work just fine. C++ changes by addition, not by removal (with tiny tiny exceptions to this rule). So you can keep your opinion.
2. It was "always" known that C++ is a work-in-progress language, and that a lot of its idioms are temporary studs until something better is formulated, implemented, tried and standardized. In a sense, we don't even have C++ yet, we're just gradually getting parts of it.
3. The most significant ones so far were in 2011, while you were still writing. (C++2020 is arguably as much of an update as C++2011.)
4. While the changes make the language larger, they also very often simplify a lot of coding tasks. A prominent example: With C++2017 you can avoid a lot of "template metaprogramming" voodoo in favor of compile-time-evaluated code.
