Yeah, I think the OP is overreacting. I am pretty sure it even says it in the initial installation instructions and gives a clear reason why it interferes with other language servers. In the "Features" section of the VsCodium extensions "Adds language features from Pyrefly's analysis like go-to definition, hover, etc. (full list here) and disables Pylance completely (VSCode's built-in Python extension)". I suspect there is an element of LLM-sycophancy-driven activism here.
