I can't point at a single reason, but I got sick of it. The interminable solves were awful. Mamba made it better, but can still be slow. Plenty of more esoteric packages are on PyPI but not Conda. (Yes, you can install pip packages in a conda env file.) Many packages have a default version and a conda-forge version; it's not always clear which you should use. In Github CI, it takes extra time to install. Upon installation it (by default) wants to mess around with your .bashrc and start every shell in a "base" environment. It's operated by another company instead of the Python Software Foundation. idk, none of these are deal-breakers, but I switched to venv and have not considered going back.
