Are you seriously arguing that R's implementation and statsmodels's implementations are doing it wrong? What if I had a model called "OrdinaryLeastSquares" in sklearn and had it regularize by default. After all, it's sklearn, so people probably wanted a penalized least squares model. That would be bad, because it's not what that means in most other libraries and textbooks where users have encountered the term.
